Syringomyelia resulting from arachnoiditis due to disseminated coccidioidomycosis meningitis has been previously established in the literature. Worsening syringomyelia after kyphotic cervical deformity correction in a patient with spinal coccidioidomycosis, however, has not yet been reported. Herein we present an extremely rare case of disseminated coccidioidomycosis with cystic cervical lesions and an associated syrinx which, after undergoing cervical kyphotic deformity correction in the setting of iatrogenic loss of cervical lordosis, experienced acute syrinx expansion requiring urgent syringosubarachnoid shunt. To our understanding, this is the first case reported of such an event., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Objective: Vertebral osteomyelitis is a rare complication of coccidioidomycosis infection. Surgical intervention is indicated when there is failure of medical management or presence of neurological deficit, epidural abscess, or spinal instability. The relationship between timing of surgical intervention and recovery of neurological function has not been previously described. The purpose of this study was to investigate if the duration of neurological deficits at presentation affects neurological recovery after surgical intervention., Methods: This was a retrospective study of all patients diagnosed with coccidioidomycosis involving the spine at a single tertiary care center between 2012 and 2021. Data collected included patient demographics, clinical presentation, radiographic information, and surgical intervention. The primary outcome was change in neurological examination after surgical intervention, quantified according to the American Spinal Injury Association Impairment Scale. The secondary outcome was the complication rate. Logistic regression was used to test if the duration of neurological deficits was associated with improvement in the neurological examination after surgery., Results: Twenty-seven patients presented with spinal coccidioidomycosis between 2012 and 2021; 20 of these patients had vertebral involvement on spinal imaging with a median follow-up of 8.7 months (IQR 1.7-71.2 months). Of the 20 patients with vertebral involvement, 12 (60.0%) presented with a neurological deficit with a median duration of 20 days (range 1-61 days). Most patients presenting with neurological deficit (11/12, 91.7%) underwent surgical intervention. Nine (81.2%) of these 11 patients had an improved neurological examination after surgery and the other 2 had stable deficits. Seven patients had improved recovery sufficient to improve by 1 grade according to the AIS. The duration of neurological deficits on presentation was not significantly associated with neurological improvement after surgery (p = 0.49, Fisher's exact test)., Conclusions: The duration of neurological deficits on presentation should not deter surgeons from operative intervention in cases of spinal coccidioidomycosis.

Clinically significant endemic mycoses (fungal infections) in the United States (U.S.) include Blastomyces dermatitidis, Histoplasma capsulatum, and Coccidioides immitis/posadasii. While the majority of infections go clinically unnoticed, symptomatic disease can occur in immunocompromised or hospitalized patients, and occasionally in immune-competent individuals. Clinical manifestations vary widely and their diagnosis may require fungal culture, making the rapid diagnosis a challenge. Imaging can be helpful in making a clinical diagnosis prior to laboratory confirmation, as well as assist in characterizing disease extent and severity. In this review, we discuss the three major endemic fungal infections that occur in the U.S., including mycology, epidemiology, clinical presentations, and typical imaging features with an emphasis on the pediatric population., (© 2023.

An elderly man without history of travel presented with complaints of intermittent fever for 2 months, cough with scanty expectoration for 15 days and history of weight loss of 5 kg in 1 year. The chest X-ray and CT scan of the thorax showed dispersed centrilobular nodules and patchy subpleural consolidation in both lungs with mediastinal lymphadenopathy. He underwent bronchoscopy and bronchoalveolar lavage culture grew Pseudomonas aeruginosa He was prescribed antibiotics based on culture sensitivity; however, patient continued to have symptoms. All relevant blood investigations were within normal limits. He underwent CT-guided biopsy of the right lung lesion during which clearing of the radio-opacities present in the initial CT scan and appearance of fresh lesions in different locations were observed. Migratory shadows were suspected. Fine-needle aspiration cytology showed features suggestive of coccidioidomycosis for which antifungals were started. After 1 month, he improved symptomatically and chest X-ray showed clearance of shadows., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2022.

Background: Pericardial disease can be a manifestation of infection and imaging can have a role in its diagnosis. coccidioidomycosis endemic fungal infection has been more frequently reported over the past few decades. Other than case reports or series, there has been no systemic study evaluating pericardial imaging findings in patients with coccidioidomycosis to the best of our knowledge. The purpose of this study was to evaluate intrathoracic computed tomographic (CT) imaging abnormalities in patients with coccidioidal infection with specific emphasis on the pericardium., Methods: Retrospective review of radiology reports and clinical chart review was performed to identify patients with coccidioidomycosis between January 2000 and September 2021 at our medical center. Diagnosis of infection was confirmed predominately with serology. Patients were excluded if a CT was not performed within 3 months of confirmed diagnosis date and if there was concomitant additional granulomatous or fungal infection. Chest CT was reviewed for pericardial and additional intrathoracic findings., Results: The final retrospective cohort consisted of 37 patients. Imaging findings included lung nodules (N = 33/37), consolidation (N = 25/37), mediastinal or hilar lymphadenopathy (N = 20/37) and pleural effusions (N = 13/37). Eleven of 37 patients (30%) had either trace pericardial fluid (N = 3/37) or small pericardial effusions (N = 8/37). One patient had pericardial enhancement/thickening and history of pericardial tamponade. No other patient had clinical pericarditis or pericardial tamponade. Pericardial calcifications were not seen in any patient. Pericardial effusion was statistically associated with presence of pleural effusion as 9/13 patients with pleural effusion had pericardial effusion versus 2/26 patients without pleural effusion had pericardial effusion (p < 0.001). Otherwise patients with and without pericardial imaging findings were similar in terms of demographics, comorbidities and other imaging findings., Conclusion: Pulmonary parenchymal pathology is a common manifestation of coccidioidal infection. Most patients with coccidioidomycosis do not have pericardial imaging abnormalities on CT., (© 2022. The Author(s).)

Histoplasmosis, blastomycosis, and coccidioidomycosis are endemic fungal infections in North America. Many infections are subclinical, and many symptomatic infections are mild. Pneumonia is the most common clinical manifestation. All can occur in immunocompetent and immunocompromised patients, with the latter at greater risk for disseminated and more severe disease. As with other acute respiratory illness, imaging can play a role in diagnosis. Knowledge of the acute and chronic imaging findings of endemic fungal infections is important for radiologists so that they can assist in establishing these often-elusive diagnoses, recognize normal evolution of imaging findings of infection, and identify complications., Competing Interests: Disclosure The author has nothing to disclose., (Copyright © 2022 Elsevier Inc.

Coccidioidomycosis is a disease found in the southwestern United States and caused by inhalation of arthroconidia of Coccidioides immitis and posadasii . Although the disease is most commonly asymptomatic or respiratory, it has a propensity to disseminate to any tissue in the body with the most common being skin, bone, joints, and central nervous system. This case demonstrates the dissemination of coccidioidomycosis to several foci along with a rare form of parenchymal dissemination with an unusual neuroradiological finding.

Coccidioidomycosis is endemic to California, Arizona, and Mexico. In recent years, the reported cases of coccidioidomycosis have increased in nonendemic regions. Here, we reported a case of imported pulmonary coccidioidomycosis in a Chinese patient. A 63-year-old man presented with dry cough and fatigue for 6 months, and a computed tomography scan revealed a solitary nodule in the right lower lung and small nodules in both lungs. The diagnosis of coccidioidomycosis was initially confirmed by histopathologic examination. The pathogen Coccidioides spp. was identified by laser capture microdissection (LCM) combined with subsequent molecular techniques based on the positive histopathologic features. Additionally, we reviewed 47 reported cases of coccidioidomycosis in China. The number of reported cases is increasing, and the incidence of disseminated infection has exhibited a trend of shifting towards healthy young adults in China. Since clinical presentations and imaging findings lack specificity, a majority of domestic cases of coccidioidomycosis were initially misdiagnosed as tumours or tuberculosis. Moreover, the diagnosis of endemic mycoses may be challenging because of their rarity and the limited availability of diagnostic tests. The diagnosis was mainly confirmed by histopathological examination. The species involved were identified based on positive cultures in only 4 cases. To our knowledge, this is the first study to use LCM and molecular techniques to identify Coccidioides spp. in the histopathologically positive but uncultivable specimen. Comparing with previous reported studies, LCM combined with nucleic acid amplification techniques improve the ability of species identification for the timely diagnosis of coccidioidomycosis.

Background: Knowledge of the clinical and magnetic resonance imaging (MRI) features of intracranial Coccidioides infection in dogs is essential for prompt diagnosis to limit disease-associated morbidity and death., Objectives: To describe the MRI appearance of intracranial coccidioidomycosis in dogs, identify associated clinical and clinicopathologic findings, and report outcomes of medical treatment., Animals: Forty-five client-owned dogs with presumed intracranial Coccidioides infection., Methods: Retrospective case series. Medical records and images were reviewed. Clinical history, examination findings, serology, imaging characteristics, treatment, and outcome were recorded. Included cases had an abnormal brain MRI and positive Coccidioides serology by agar-gel-immunodiffusion (AGID)., Results: Median age was 7-years. Generalized tonic-clonic seizures were the most common presenting sign (25/45). Two lesion categories were identified: a granulomatous form with 1 or more distinct, intra-axial, contrast-enhancing foci (37/45), and a second variation with diffuse, bilateral, symmetrical lesions of the caudate nuclei and frontal lobes (8/45). Serum IgG titers ranged from 1 : 1 to ≥ 1 : 256; 2 dogs had positive IgM titers at 1 : 2. All dogs with follow-up serology (34/45) had a reduction in titer. Mean duration of follow-up was 22.4 ± 20.5 months (median 16 months). Six dogs were lost to follow-up <1-year after diagnosis (median 9 months). Five dogs were clinically well but had yet to be followed for >1-year. Of the remaining 34 dogs, 28 (82%) were alive ≥ 1-year after diagnosis. Thirteen of these dogs had follow-up times ≥ 2-years., Conclusions and Clinical Importance: The prognosis for intracranial Coccidioides infection is generally more favorable with medical treatment than in earlier reports., (© 2021 The Authors.

The digitization of radiographic studies along with high-speed transmission of images has formed the basis of teleradiology, which has become an integral component in the workflow of a contemporary radiology practice. It is with this advent and growing utilization of teleradiology that the significance of the source location of images has gained importance. Specifically, the importance of where the patient resides and what endemic fungi occur in that location cannot be underestimated. In the United States, histoplasmosis, coccidioidomycosis, blastomycosis, and cryptococcosis are caused by endemic fungi occurring in the Ohio and Mississippi river valleys, the Southwest, the Upper Midwest, and the Pacific Northwest, respectively. All of these organisms enter the body through the respiratory system and have the potential to cause significant morbidity and mortality. Patients infected with these fungi are often asymptomatic but may present with acute flulike symptoms such as fever, cough, or dyspnea. Patients may also present with vague chronic symptoms including cough, fever, malaise, and weight loss. Thoracic manifestations at radiography and CT include consolidation, nodules, cavities, lymphadenopathy, and pleural disease. PET may show fluorine 18-fluorodeoxyglucose uptake with active acute or chronic infections, and it is difficult to distinguish infections from malignancy. Imaging findings may be nonspecific and can be confused with other disease processes, including malignancy. The patient demographics, clinical history, and location are clues that may lead to a proper diagnosis of endemic fungal disease. The radiologist should be cognizant of the patient location to provide a correct and timely radiologic diagnosis that helps guide the clinician to initiate appropriate therapy. © RSNA, 2021.

Introduction: Coccidioidomycosis, a disease caused by Coccidioides immitis or Coccidioides posadasii, is endemic in arid climatic regions in Northeast Brazil. Its prevalence is higher among young adult males living in rural areas. Existing literature about this disease in Ceará, a Northeast Brazilian state, are scarce. Here, we aimed to outline the clinical and epidemiological profiles, radiological patterns, and therapeutic responses of patients with coccidioidomycosis in a reference center in Ceará, Brazil., Methods: This is a descriptive study with quantitative analysis. Patients who underwent medical follow-up in São José Hospital of Infectious Diseases and received confirmed mycological diagnosis of coccidioidomycosis between January, 2007 and December 2017 were included. Epidemiological, clinical, radiological, and therapeutic response data were collected from medical charts., Results: Thirty patients were included. The patients were males with median age of 30 years, and 73% were considered to have high-risk exposure to Coccidioides owing to professional activities. Cough (96.7%), dyspnea (63.3%), fever (86.7%), and pleuritic pain (60%) were the most prevalent clinical manifestations. Interstitial pattern (91.3%) was the most frequent pulmonary radiological finding. Fluconazole, amphotericin B, and itraconazole were administered for treatment (in 82.1%, 42.8%, and 21.4% of cases, respectively). A favorable outcome was observed in 83.8% of patients., Conclusions: Coccidioidomycosis was more prevalent in the central and southern regions of the State of Ceará. Understanding the local epidemiology and clinical manifestations of the disease, in addition to the pulmonary radiologic findings, may aid the early detection of coccidioidomycosis and facilitate early diagnosis.

Background: Coccidioidal meningitis is a life-threatening condition and a diagnostic challenge in cases of chronic meningitis. It is associated to severe complications, like basal arachnoiditis, hydrocephalus, and secondary vasculitis., Objective: To present a 20-year retrospective clinical series of coccidioidal meningitis cases at a Mexican neurological referral center., Results: The clinical records of 11 patients, predominantly males, were retrieved. Weight loss and night sweats were observed in 64 % of cases. Neurological signs included intracranial hypertension in 91 % of cases, altered alertness and meningeal syndrome in 72 %, and neuropsychiatric symptoms in 64 %. Mean CSF glucose levels were 30 ± 25 mg/dL, and pleocytosis ranged from 0 to 2218 cells/mm 3 . The diagnosis was confirmed by coccidioidal antigen latex agglutination in 91 % of cases. Radiological findings were hepatomegaly in 55 % of cases and pneumonia in 45 %. Neuroimaging findings included leptomeningitis in 73 % of cases, pachymeningitis in 45 %, and vascular involvement in 91 %. Less common findings included spinal cord lesion and mycotic aneurism, found in 18 % of cases. A molecular coccidioidal DNA test confirmed the predominance of Coccidioides immitis, detected in 64 % of cases. With respect to the clinical outcome, 46 % of patients died. The survivors suffered from sequels like chronic headache, cognitive alterations, and depression., Conclusions: Coccidioidal meningitis is an entity with high mortality rates. More than one half of patients suffered disseminated disease. Although meningeal signs are not frequent in chronic meningitis, more than two-thirds of our patients showed mild nuchal rigidity. In addition, cerebral and cerebellar volume loss, associated with cognitive impairment and depression, was often observed in surviving patients during the clinical-radiological follow-up., (Copyright © 2020 Elsevier B.V.

The full geographic range of coccidioidomycosis is unknown, although it is most likely expanding with environmental change. We report an apparently autochthonous coccidioidomycosis patient from Spokane, Washington, USA, a location to which Coccidioides spp. are not known to be endemic.

Coccidioidomycosis is an endemic disease of arid regions in the Western hemisphere. Its clinical presentation varies from asymptomatic nodules on chest x-rays to disseminated disease. We present the case of a 48-year-old man with a hard and heterogeneous tumor in the posterior aspect of the right testis. Color flow doppler testicular ultrasonography was performed and two nodular masses in the tail of the right epididymis were identified. An epididymectomy was performed and histopathological examination revealed coccidioidomycosis. After diagnosis, the patient was successfully treated with fluconazol.

Introduction: Systemic endemic mycoses are prevalent in specific geographical areas of the world and are responsible for high rates of morbidity and mortality in these populations, and in immigrants and travelers returning from endemic regions. The most common fungal infections that can affect the lungs of immunocompetent patients include histoplasmosis, coccidioidomycosis, paracoccidioidomycosis, blastomycosis, sporotrichosis, aspergillosis, and cryptococcosis. Diagnosis and management of these diseases remain challenging, especially in non-endemic areas due to the lack of experience. Therefore, recognition of the various radiologic manifestations of pulmonary fungal infections associated with patients' clinical and epidemiologic history is imperative for narrowing the differential diagnosis. Areas covered: This review discusses the clinical and radiological findings of the main endemic fungal diseases affecting the lungs in immunocompetent patients. Specific topics discussed are their etiology, epidemiology, pathogenesis, clinical manifestations, methods of diagnosis, pathology and main imaging findings, especially in computed tomography. Expert commentary: Imaging plays an important role in the diagnosis and management of pulmonary fungal infection and may reveal useful signs. Although definitive diagnosis cannot be made based on imaging features alone, the use of a combination of epidemiologic, clinical and imaging findings may permit the formulation of an adequate differential diagnosis.

Background: Coccidioidal meningitis can progress to vasculitis with aneurysm formation. Although aneurysmogenesis is rare, it carries exceptionally high mortality. Except in one instance, prior case reports have documented universally fatal consequences., Case Description: A 26-year-old man developed disseminated coccidioidomycosis with formation of multiple aneurysms throughout the anterior intracranial vasculature bilaterally. This report is unique in that it chronicles the formation and subsequent spontaneous thrombosis of several aneurysms over a 4-week period. In total 10 aneurysms were documented in the same patient-the highest reported to date. The patient was eventually discharged from the hospital for what has heretofore been a universally fatal disease process. Neurologic examination and vascular imaging 1 month after discharge demonstrated stable findings., Conclusions: Coccidioidal aneurysms carry a high mortality. The mainstay of therapy remains lifelong triazole antifungal therapy with the addition of liposomal amphotericin in cases of treatment failure. Steroid use is controversial but should be considered whenever there is vascular involvement. Although watchful waiting is reasonable in light of the possibility of spontaneous thrombosis with medical management, dynamic changes in aneurysm size or configuration should prompt timely endovascular or operative interventions., (Copyright © 2018 Elsevier Inc.

Coccidioidomycosis is an invasive fungus found primarily in the soil of Southwestern United States, Mexico, and Central America. Primary disease mostly presents as a pulmonary disease although multiple organ systems can be affected through lymphohematogenous dissemination, with ocular seeding extremely rare. When present, the anterior segment structures are most commonly affected. Isolated choroid and/or vitreal disease has been reported infrequently. This is a case of chorioretinitis with vitreal involvement.

The neurological examination findings, clinical pathology (including Coccidioides immitis IgG/IgM serology) and magnetic resonance imaging (MRI) findings in 13 dogs with a novel form of intracranial coccidioidomycosis are described in a retrospective case series, with long-term clinical resolution documented in 11/13 dogs (84.6% of cases) with oral fluconazole therapy. The medical records of the Veterinary Neurological Center in Phoenix, Arizona from the years 2000 to 2017 were utilized to search for dogs with appropriate inclusion criteria. Magnetic resonance imaging findings were highly consistent across all cases and characteristically demonstrated bilaterally symmetric T2 hyperintensity throughout the frontal lobes, caudate nuclei, and rostral internal capsule, ±faint, wispy contrast enhancement on T1-postcontrast images. These findings were in stark contrast to previously reported MRI findings in dogs with intracranial coccidioidomycosis, which were typically characterized by a focal, strongly contrast enhancing granuloma and extensive vasogenic edema, typically unilateral. Schnauzer breeds represented eight of 13 (61.5%) cases, possibly suggesting a breed predilection. Three cases underwent repeat MRI after resolution of neurological signs and documentation of a decreased Coccidioides titer in response to fluconazole therapy. All demonstrated complete resolution of previously identified lesions, but with marked, severe atrophy of the caudate nuclei and frontal lobes bilaterally. Findings from this study document a variant appearance for intracranial coccidioidomycosis that, to the author's knowledge, has not been previously described in dogs. Authors propose that, although this variant demonstrates extensive pathological changes within the forebrain, the clinical outcome and response to treatment is favorable in a majority of cases., (© 2018 American College of Veterinary Radiology.)

Background and Purpose: Coccidioides immitis is a dimorphic fungus endemic to the Southwest United States and Mexico, and at our institution, it is a relatively common pathogen presenting with a broad spectrum of associated spine diseases. We describe the various spinal manifestations resulting from coccidioidal infection and provide MR imaging examples from 41 pathologically proved cases., Materials and Methods: Retrospective electronic medical record and PACS searches were performed. Patients found to have both MR imaging findings positive for infection and confirmative biopsy and/or CSF studies were included. Abnormal MR imaging findings were identified, categorized, and quantified. Patient demographics and associated intracranial involvement if present were also recorded., Results: Forty-one patients were included. Positive findings were categorized as leptomeningeal enhancement (26 patients, 63%), arachnoiditis (22 patients, 54%), osteomyelitis-discitis (14 patients, 34%), cord edema (11 patients, 27%), and true syrinx (3 patients, 7%). Thirty patients had documented brain involvement (73%), most commonly in the form of basilar meningitis. Four patients were positive for HIV (10%). Fifteen patients had pulmonary manifestations at presentation (37%)., Conclusions: C immitis results in various spinal manifestations, most commonly leptomeningeal enhancement and arachnoiditis/adhesive disease followed by osteomyelitis, which may resemble tuberculous or pyogenic infection on MR imaging., (© 2018 by American Journal of Neuroradiology.)

We report a case of imported pulmonary coccidioidomycosis caused by Coccidioides posadasii in a patient who was misdiagnosed as tuberculosis and mistreated with antituberculosis medications for 18 months. The symptoms were not relieved until antifungal treatment was started. An extensive review of the coccidioidomycosis cases occurring in China reveals 38 cases, 16 of which had no associated history of travel to any traditional endemic areas. We speculate that some factors may drive Coccidioides spp. transference to China, which then causes those domestic infections. Moreover, we indicate the first, to the best of our knowledge, possible endemic areas in China., (© 2018 Blackwell Verlag GmbH.)

The case of a 60 year old woman with hemoptysis and a thin-walled cavitary lesion at the upper lobe of the right lung is presented. The woman presented at the Mycology Unit of the Muñiz Hospital in Buenos Aires City 3 months after the beginning of her clinical manifestations. A hyaline micelial fungus with chlamido-arthroconidias was isolated from the bronchoalveolar lavage. Immunodiffusion and counter-immnunoelectrophoresis with coccidioidin and histoplasmin rendered positive results against both antigents, and skin tests with coccidioidin and histoplasmin were also positive with strong reactions. The isolated fungus was identified as Coccidioides posadasii at the National Microbiology Institute Carlos Malbrán, by means of a molecular technique. The patient was treated with itraconazole by oral route at a daily dose of 200mg with good clinical response, but due to the persistence of the lung cavity, a surgical removal of the upper lobe of the right lung had to be scheduled., (Copyright © 2017 Asociación Española de Micología.

Case Presentation: A previously healthy 62-year-old woman was transferred to the ICU from the medical ward with acute bronchospastic respiratory failure requiring intubation and mechanical ventilation. Four weeks before, the patient was vacationing in Arizona and acquired a mildly productive cough as well as mild dyspnea. She presented to an urgent care facility and was diagnosed with community-acquired pneumonia. She received a 5-day course of azithromycin, with partial improvement of her symptoms. The patient returned home 1 week prior to admission, reporting worsening dyspnea, chest pressure, cough, and fever. The patient was admitted to the medical ward, and treatment for unresolved pneumonia was begun with levofloxacin, an inhaled short-acting beta agonist, and oral prednisone. Despite this treatment, the patient experienced severe respiratory distress with audible wheezing as well as increased work of breathing. She was intubated for acute hypoxemic respiratory failure and transferred to the ICU., (Copyright © 2017 American College of Chest Physicians. Published by Elsevier Inc. All rights reserved.)

Invasive fungal disease (IFD) is a life-threatening condition, especially in immunocompromised children. The role of diagnostic imaging in children at risk for an IFD is multifactorial, including initially detecting it, evaluating for dissemination of infection beyond the primary site of disease, monitoring the response to antifungal therapy, and assessing for potential relapse. The objective of this review was to synthesize the published literature relevant to the use of various imaging modalities for the diagnosis and management of IFD in children., (© The Author 2017.

Coccidioidomycosis (valley fever) is a systemic fungal infection resulting from inhalation of the Coccidioides immitis or posadasii spores. In many cases, infection causes a self-limited community-acquired pneumonia; however, in patients with risk factors, such as immunosuppression or African or Pacific Island ancestry, significant morbidity and mortality from disseminated disease may occur. Presented here are comparative images using Tc-MDP bone scan, F-FDG PET/CT, and MRI. Each demonstrates particular strengths, which aid in assessing the extent of systemic involvement of a biopsy-proven case of disseminated coccidioidomycosis.

Background: Coccidioidomycosis is a fungal infection that usually presents as a primary lung infection. The fungus is endemic to the Southwest United States of America, northern Mexico and parts of Central and South America the infection is rare outside these areas. However, some patients develop disseminated infection that can lie dormant for several years and can present itself in travelers. We report the first case of extra pulmonary Coccidioidomycosis in a non-immunocompromised individual in Denmark., Case Presentation: A 32 year old Danish woman presented at the Emergency department with abdominal pain. Computed tomography scan and ultrasound examination of the pelvis raised suspicion of salpingitis. A laparoscopy exposed a necrotic salpinx and several small white elements that resembled peritoneal carcinomatosis. Histological workup however determined that she suffered from disseminated coccidioidomycosis. The patient had lived 2 years in Las Vegas, in the United States of America, 7 years prior and had no memory of lung infection at the time., Conclusions: Disseminated coccidioidomycosis is rare in non-immunocompromised individuals. The patient in this case underwent several rounds of in vitro fertilization treatment in the years before admittance. We suspect that the hormonal treatment in combination with low-dose prednisolone may have triggered reemergence of the disease and present literature that support this.

Background: Coccidioidomycosis, commonly called "valley fever," "San Joaquin fever," "desert fever," or "desert rheumatism," is a multi-system illness caused by infection with Coccidioides fungi (C. immitis or C. posadasii). This organism is endemic to the desert Southwest regions of the United States and Mexico and to parts of South America. The manifestations of infection occur along a spectrum from asymptomatic to mild self-limited fever to severe disseminated disease., Methods: Review of the English-language literature., Results: There are five broad indications for surgical intervention in patients with coccidioidomycosis: Tissue diagnosis in patients at risk for co-existing pathology, perforation, bleeding, impingement on critical organs, and failure to resolve with medical management. As part of a multidisciplinary team, surgeons may be responsible for the care of infected patients, particularly those with severe disease., Conclusion: This review discusses the history, microbiology, epidemiology, pathology, diagnosis, and treatment of coccidioidomycosis, focusing on situations that may be encountered by surgeons.

Purpose: The aim of this report was to present the first known case of coccidioidomycosis involving the temporomandibular joint, review the literature regarding dissemination to the mandible, and to provide treatment recommendations for this challenging condition., Methods: Coccidioidomycosis of the mandibular condyle was identified in a 30-year-old Somali male residing in Arizona. Due to the difficulty of surgical access and the anticipated temporomandibular joint morbidity of radical condylar debridement, primary medical management was performed., Results: Marked symptomatic improvement was observed after 10 days of IV antifungal therapy. Resolution of the abscess with residual bony destruction was observed on CT scan. Based on the results of this patient and review of the literature, an algorithm is presented to help guide management of coccidioidomycosis dissemination to the mandible., Conclusion: Prolonged antifungal therapy should be attempted for initial management of a Coccidioides abscess involving the condyle with early surgical intervention reserved for the more easily accessible and less functionally compromising portions of the mandible.

Coccidioidomycosis is an infection caused by inhalation of the Coccidioides fungus. Most infections remain subclinical or are confined to the pulmonary system. Disseminated disease is rare. Traditionally, a combination of imaging modalities has been used to determine disease extent. We suggest (18)F-FDG PET/CT as a single first-line imaging examination to assess disease extent. We present a case of disseminated coccidioidomycosis to the lung, mediastinum, soft tissues, and skeletal system. To our knowledge, no prior case reports demonstrate such widespread disease using PET/CT., (© 2016 by the Society of Nuclear Medicine and Molecular Imaging, Inc.)

Lymphadenopathy is a common radiological finding in many thoracic diseases and may be caused by a variety of infectious, inflammatory, and neoplastic conditions. This review aims to describe the patterns of mediastinal and hilar lymphadenopathy found in benign diseases in immunocompetent patients. Computed tomography is the method of choice for the evaluation of lymphadenopathy, as it is able to demonstrate increased size of individual nodes, abnormalities of the interface between the mediastinum and lung, invasion of surrounding fat, coalescence of adjacent nodes, obliteration of the mediastinal fat, and hypo- and hyperdensity in lymph nodes. Intravenous contrast enhancement may be needed to help distinguish nodes from vessels. The most frequent infections resulting in this finding are tuberculosis and fungal disease (particularly histoplasmosis and coccidioidomycosis). Sarcoidosis is a relatively frequent cause of lymphadenopathy in young adults, and can be distinguished from other diseases - especially when enlarged lymph nodes are found to be multiple and symmetrical. Other conditions discussed in this review are silicosis, drug reactions, amyloidosis, heart failure, Castleman's disease, viral infections, and chronic obstructive pulmonary disease., (Copyright © 2016 Elsevier Ltd.

Coccidiodomycosis is a disease caused by the spores of the fungi coccidiodes immitis and pulmonary coccidiodomycosis comes after inhalation of the spores which are mainly found in desert areas of the United States, central and South America. Reported cases from outside the endemic areas have always history of travel to these areas. There are no reports so far from Ethiopia or the whole Africa. We report here a case of pulmonary coccidodomycosis with no history of travel to such areas. A 24 years old female patient from Samre, South-Eastern Tigray, presented with right side chest pain and productive cough of yellowish sputum which sometimes is blood streaked. She had completed anti-tuberculosis treatment without any improvement. With a preliminary diagnosis of pulmonary mass, surgical exploration was made and histology of the excised tissue showed appedrances consistent with pulmonary coccidioidomycosis. There was marked clinical and radiological improvement after three weeks of treatment with ketoconazole. Though there are no reported cases from Ethiopia and Africa as a whole, Coccidiodomycosis should be considered as differential diagnosis especially for patients from arid areas like that of our patient before any empirical treatment.

Coccidioidomycosis is a fungal infection caused by the Coccidioides species, which is endemic in the deserts of the southwestern region of the United States, northern Mexico, and in some areas of Central and South America. We describe a case of pulmonary coccidioidomycosis in a 49-year-old Italian man who came to our hospital with fever and joint and muscle pain 10 days after his return to Italy from Venezuela. Computer Tomography revealed multiple bilateral pulmonary nodules with mediastinal lymphadenopathy. Pulmonary coccidioidomycosis was diagnosed by a serological test, and fluconazole was immediately started. The patient improved within 2 weeks, with complete clinical recovery after 6 months of therapy. This case appears to be part of a large serologically unconfirmed outbreak. In order to provide early diagnosis and treatment, healthcare providers should be aware of coccidioidomycosis, even in travellers returning home from short trips to endemic areas.

Background: Within a coccidioidal endemic region, pulmonary nodules due to coccidioidomycosis are common. Uptake of (18)fluorodeoxyglucose ((18)FDG) by positron emission tomography with computed axial tomography (PET/CT) has been used to assess whether pulmonary nodules are malignant but inflammatory lesions can be positive. The purpose of this study was to compare by PET/CT the (18)FDG uptake in pulmonary nodules likely due to coccidioidomycosis to that of nodules shown to be malignant among patients living in a coccidioidal endemic region., Methods: We retrospectively reviewed patients who underwent a PET/CT at the Southern Arizona Veterans Affairs Health Care System between January 2008 and March 2012 who were subsequently found on biopsy to have pulmonary nodules that were coccidioidal or granulomatous or were due to malignancy., Results: Among 245 diagnostic biopsies where the subject had a previous PET/CT, 15 (6.1 %) were either coccidioidal (n = 12) or granulomatous without an identified organism (n = 3). The median maximum standard unit of uptake (SUV(max)) on PET/CT of coccidioidal or granulomatous lesions was 2.0 compared to 9.8 for malignant lesions (P < 0.001). The maximum diameter of the coccidioidal or granulomatous nodules was 2.1 cm compared to 3.0 cm for the malignant lesions (P = 0.009). On multivariable analysis, an elevated SUV(max) was the only distinguishing feature between the malignant and the granulomatous lesions (OR 1.28, 95 % CI 1.05-1.55; P = 0.013)., Conclusions: Coccidioidal pulmonary nodules take up significantly less (18)FDG than those due to malignancies, but there is considerable overlap between granulomatous and malignant lesions at lower SUV(max).

Pulmonary coccidioidomycosis is a fungal disease endemic to the desert regions of the southwestern United States, Mexico, Central America, and South America. The incidence of reported disease increased substantially between 1998 and 2011, and the infection is encountered beyond the endemic areas because of a mobile society. The disease is caused by inhalation of spores of Coccidioides species. Individuals at high risk are those exposed to frequent soil aerosolization. The diagnosis is established by direct visualization of mature spherules by using special stains or cultures from biologic specimens. Serologic testing of anticoccidioidal antibodies is used for diagnosis and treatment monitoring. The infection is self-limited in 60% of cases. When the disease is symptomatic, the lung is the primary site of involvement. On the basis of clinical presentation and imaging abnormalities, pulmonary involvement is categorized into acute, disseminated, and chronic forms, each with a spectrum of imaging findings. In patients with acute disease, the most common findings are lobar or segmental consolidation, multifocal consolidation, and nodules. Adenopathy and pleural effusions are also seen, usually in association with parenchymal disease. Disseminated disease is rare and occurs in less than 1% of patients. Pulmonary findings are miliary nodules and confluent parenchymal opacities. Acute respiratory distress syndrome is an infrequent complication of disseminated disease. The acute findings resolve in most patients, with chronic changes developing in approximately 5% of patients. Manifestations of chronic disease include residual nodules, chronic cavities, persistent pneumonia with or without adenopathy, pleural effusion, and regressive changes. Unusual complications of chronic disease are mycetoma, abscess formation, and bronchopleural fistula. Patients in an immunocompromised state, those with diabetes mellitus, pregnant women, and those belonging to certain ethnic groups may show severe, progressive, or disseminated disease., (©RSNA, 2014.)

Coccidioidomycosis is a common cause of community-acquired pneumonia in the southwest United States, Mexico, and South America. The disease has seen a marked increase in incidence in the western United States in the last decade and can be acquired by individuals who travel even briefly through an endemic area, presenting a diagnostic dilemma for clinicians who are not familiar with the disease. The clinical and radiographic manifestations of pulmonary coccidioidomycosis often mimic those of other causes of pneumonia. However, because treatment recommendations and the potential for chronic sequelae of acute infection differ substantially from those for bacterial community-acquired pneumonia, accurate, timely diagnosis of coccidioidomycosis is paramount. A number of diagnostic tests are available with varying sensitivity and specificity, making the approach complex. Radiographic features, although nonspecific, sometimes demonstrate patterns more suggestive of coccidioidomycosis than bacterial community-acquired pneumonias. A routine blood count may reveal eosinophilia. Serologic testing is used most widely but may be negative early in the course of disease, potentially leading to misdiagnosis with subsequent inappropriate treatment and follow-up. The sensitivity of serologic testing is lower in immunocompromised patients, a population at the highest risk for developing severe disease. When clinically appropriate, other biologic specimens, such as sputum, bronchoalveolar lavage fluid, or lung biopsies, may allow for rapid, definitive diagnosis. In light of the significantly increased incidence and complexities in diagnosis of coccidioidomycosis, we examine the diagnostic approach and provide examples of classic clinical and radiographic presentations, discuss the utility of serologic testing, and suggest algorithms that may aid in the diagnosis.

Objective: Mycotic aneurysm rupture has been described as a rare, universally fatal complication of central nervous system Coccidioides immitis meningitis. Recently, however, we reported the successful surgical management of a midbasilar dissecting mycotic aneurysm related to C. immitis meningitis in a 24-year-old pregnant woman with acquired immune deficiency syndrome., Methods: A 24-year-old pregnant woman with known acquired immune deficiency syndrome and a history of C. immitis meningitis presented to our institution with subarachnoid and intraventricular hemorrhage. Diagnostic cerebral angiography revealed a dissecting, midbasilar aneurysm involving the right anterior inferior cerebellar artery and causing stenosis of the proximal basilar artery. Through a retrosigmoid craniotomy, clip reconstruction of the basilar artery under hypothermic circulatory arrest was performed. The patient was neurologically intact at discharge (postoperative day 19) with the exception of mild disconjugate gaze and headache., Results: At her 53-month follow-up, the patient was neurologically intact with only mild disconjugate gaze on upgaze. There was no evidence of local aneurysm recurrence or regional aneurysm formation, and the basilar artery was patent. Her C. immitis meningitis was well controlled. The patient is maintained on oral highly active antiretroviral therapy and an antifungal regimen., Conclusions: Our patient represents the only survivor of a C. immitis mycotic aneurysm rupture. In her case, long-term clinical and radiographic stability were achieved through a vigilant multidisciplinary approach., (Copyright © 2013 Elsevier Inc. All rights reserved.)

A 43 year-old diabetic woman, who suffered chronic cough and brown expectoration, is presented in this clinical problem. X-ray exam and CT thorax scan showed a cavitary lung lesion, located at the upper field of the left lung. This lesion had 5 cm in diameter, with a thick wall and a spherical shadow inside. The diagnosis of chronic cavitary pulmonary coccidioidomycosis was based on the isolation of Coccidioides sp. from cultures of expectoration and bronchoalveolar lavage, and the detection of specific antibodies in immunodiffusion test and counterimmunoelectrophoresis with coccidiodin. Her diabetes was not well controlled. She was treated with intravenous amphotericin B and oral itraconazole, with good clinical response; after four months of treatment the patient abandoned clinical controls. We suppose that the patient presented a coccidioidal fungus ball, inside a chronic cavitary lesion due to pulmonary coccidiodomycosis. She came from an endemic zone of coccidioidomycosis in the Northwest of the Argentine Republic (Catamarca Province)., (Copyright © 2012 Revista Iberoamericana de Micología.

Coccidioidomycosis is an endemic disease of the western hemisphere. In cases occurring in non-endemic areas, eliciting a history of exposure as well as a high index of suspicion is imperative for timely and accurate diagnosis. In this case, a 65-year-old male presented to our hospital with fever, dry cough and malaise, and on X-ray chest, was found to have a lower lobe consolidation left lung with nodular lesions in both lungs and necrotic mediastinal lymphadenopathy. He lived in Arizona, USA, for 6 months before admission. Pulmonary coccidioidomycosis was confirmed by the isolation of Coccidioides spp. in pure culture from both broncho-alveolar lavage and lung biopsy specimens. The identity of the isolate was confirmed as C. posadasii by gene sequencing. The patient improved after being treated with fluconazole.

A 64-year-old man, resident in Arizona for 3&emsp14;years, presented with a week-long history of a dry cough and 'flu-like symptoms'. He had recently been renovating his house. A chest radiograph showed a left mid-zone opacity. Investigations for lung cancer were performed and he underwent CT-guided biopsy of the lesion. A coccidioidal fungus known to cause 'Valley Fever' was isolated. Treatment with fluconazole led to a complete recovery. This fungal infection is endemic in parts of the USA and Mexico and usually presents with respiratory symptoms. Additional complications include disseminated disease and meningitis.

Granuloma annulare (GA) is a reactive process in the dermis, related to degeneration of collagen. It may occur as an idiopathic phenomenon or in conjunction with a myriad of systemic conditions, including infectious disease. We report an interesting case of GA precipitated by pulmonary coccidioidomycosis.
