Background: Acute suppurative thyroiditis is a rare and potentially life-threatening disease. A few cases of acute suppurative thyroiditis associated with thyrotoxicosis have been reported in adults. We report a case of acute suppurative thyroiditis that was associated with thyrotoxicosis., Case Presentation: We report the case of a 49-year-old Iranian female presented with a painful neck swelling for a week. Computed tomography showed a well-defined gas-filled collection in the left thyroid lobe with an enhancing margin. The patient underwent two-phase surgery, first left thyroid abscess drainage and then total thyroidectomy. The result of histopathology examination was multinodular goiter with abscess formation without malignancy., Conclusion: Abscess formation and thyrotoxicosis is a very rare condition that occurs at the same time in acute suppurative thyroiditis. Despite antibiotic therapy being the first line of treatment, surgery is also required when antibiotic therapy fails., (© 2023. BioMed Central Ltd., part of Springer Nature.)

Acute suppurative thyroiditis are infrequent infections, although their early and proper management are needed to reduce complications and recurrences. We review the clinical presentation, etiology, clinical outcome and management of 9 cases of thyroid infections diagnosed in children, and analyze the existence of predisposing factors for these infections., Competing Interests: The authors have no funding or conflicts of interest to disclose., (Copyright © 2023 Wolters Kluwer Health, Inc.

Background: Pyriform sinus fistulas (PSFs) are rare congenital anomalies of the third or fourth brachial pouch. Dyspnea is reportedly secondary to compression by a neck mass. However, hoarseness, as the first symptom of PSF, has not yet been reported., Case Presentation: This report describes an 11-year-old girl presenting with hoarseness as the first symptom of PSF. Hoarseness occurred 2 days prior to admission. On admission, she had fever, hoarseness, and an elastic soft mass on her left anterior neck. Contrast-enhanced computed tomography of the cervical region demonstrated an abscess partially infiltrating the thyroid gland and an air pocket near the pyriform sinus. Pharyngoscopy revealed swelling of the left arytenoid region, with purulent retention. The left vocal cord was swollen but not paralyzed. Additionally, the laboratory data indicated thyrotoxicosis. Suspecting a PSF infection, parenteral treatment with cefotaxime and dexamethasone was initiated. On the following day, the hoarseness disappeared, and the fever resolved. Four weeks after onset, the thyroid hormone levels returned to the normal range, and a barium esophagogram revealed residual contrast in the left pyriform sinus, leading to a diagnosis of PSF., Conclusion: PSF presenting with hoarseness as the first symptom in patients should be considered., (© 2023.

Acute suppurative thyroiditis is a rare and potentially life-threatening cause of thyroid inflammation requiring prompt recognition and management. There are few reported cases of thyrotoxicosis due to acute suppurative thyroiditis. We are reporting the case of a 9-year-old boy who presented to the emergency room with fevers, neck pain and swelling, night terrors, and emotional lability. He was hemodynamically stable with initial lab work remarkable for neutrophilia without leukocytosis, elevated inflammatory markers, and hyperthyroidism. Imaging of the neck revealed a heterogenous collection in the region of the left thyroid concerning for suppurative thyroiditis and adenitis. He was admitted to the hospital and initiated on intravenous antibiotics. Given lack of significant improvement in pain, he was taken to the operating room for drainage on hospital day 4 with remarkable clinical improvement in pain. He was discharged on oral antibiotics. Lab work obtained on postoperative day 15 showed resolution of hyperthyroidism and decreasing inflammatory markers. Subsequent imaging following resolution of the acute illness did not reveal any anatomic abnormality that may have predisposed him to developing acute suppurative thyroiditis. Thyrotoxicosis as a complication of acute suppurative thyroiditis is a rare occurrence, and is thought to be due to the release of preformed thyroid hormone from damaged thyroid follicles. The thyrotoxic state is often transient and resolves with appropriate management of acute suppurative thyroiditis. This complication is important to recognize, as failure to appropriately diagnose and treat acute suppurative thyroiditis can lead to poor outcomes, such as airway compromise and death.

Suppurative thyroiditis is uncommon in the pediatric population and particularly rare to be caused by fungi. We present a case of Candida tropicalis thyroiditis in an adolescent male with acute lymphocytic leukemia that led to disseminated candidiasis, thyroid storm and eventual total thyroidectomy for source control.

Acute suppurative thyroiditis (AST) leading to thyroid abscess is a rare clinical entity. The aim of this article is to demonstrate a case of severe bilateral pneumonia which originated from a thyroid abscess. The authors report the case of a 57-year-old woman with severe bilateral pneumonia of thyroid origin. The patient had a painful throat and dysphagia for 2 or 3 days. She also had a history of mild fever and hard breathing with a discreet cough 7 days prior to hospital admission. In the past few months, the patient had frequent pneumonias. The patient was treated with a culture-appropriate antibiotic and total thyroidectomy. Primary recommendations for treatment of complicated infections of thyroid origin consider a multidisciplinary approach. Recurrent pneumonia in patients with thyroid nodules may be the result of thyroid inflammation, and, in such patients, neck ultrasound should be conducted as part of the diagnostic workup., (© 2018 The Author(s).

In immunocompromised patients, Aspergillus infections are important causes of morbidity and mortality. We describe a patient with cryoglobulinemic vasculitis who developed disseminated invasive aspergillosis with thyrotoxicosis caused by Aspergillus fumigatus. The diagnosis was based upon radiological, microbiological and pathological findings. The patient was treated successfully with voriconazole and caspofungin treatment followed by total thyroidectomy. We provide an overview of published reports on Aspergillus thyroiditis with an emphasis on therapeutic approaches.

A 60-year-old woman with diabetes and symptomatic urinary tract infection presented to us with a painful neck swelling for 2 weeks. We discuss diagnostic and management issues in acute suppurative thyroiditis caused by Escherichia coli., (2016 BMJ Publishing Group Ltd.)

Background: Piriform sinus tract (PST) is a rare congenital condition. A delay in diagnosis is common leading to recurrent inflammation., Method: A retrospective review was performed on all cases of PST treated at a tertiary referral centre between May 1997 and May 2012., Results: Eighteen patients were reviewed with a mean age of 5.4years at presentation (ranged from 0day to 14years). Most patients presented as acute inflammation (88.9%) and 16 had a left sided lesion. 72.2% of the PST are identified by contrast swallow study. The diagnostic yield was significantly higher if the study was done after the initial acute inflammation settled. Ultrasonography and computer tomography are less sensitive. The median duration from presentation to diagnosis was 17.6months (ranged 0-120months). Ten patients (55.6%) experienced recurrent inflammation before confirming the diagnosis. Fistulectomy alone was performed in 15 patients while an additional en-bloc hemithyroidectomy was done in 2 patients., Conclusion: PST should be suspected in children presenting with a left deep neck abscess. Contrast swallow study is very effective in making diagnosis but has to be postponed after the acute inflammation settles. The condition can be effectively treated by fistulectomy without hemithyroidectomy in majority of our cases., (© 2013.)

Riedel's thyroiditis (RT) is a rare chronic inflammatory disease of the thyroid gland. It is characterized by a fibroinflammatory process that partially destroys the gland and extends into adjacent neck structures. Its clinical manifestation can mask an accompanying thyroid neoplasm and can mimic invasive thyroid carcinoma. Therefore, diagnosis can be difficult prior to surgical removal of the thyroid, and histopathologic examination of the thyroid is necessary for a definite diagnosis. The concurrent presence of RT and other thyroid diseases has been reported. However, to our knowledge, the association of RT with acute suppurative thyroiditis and micropapillary carcinoma has not been reported. We report a rare case of concurrent RT, acute suppurative thyroiditis, and micropapillary carcinoma in a 48-year-old patient.

We report two children with acute suppurative thyroiditis (AST). They presented with typical features of AST, which include fever, painful goiter and biochemical euthyroidism. An anatomical defect predisposed to thyroid infection, pyriform sinus fistula, was identified in one patient. Both patients responded well to surgical pus drainage and antibiotic treatment. Anatomical defects must be sought in all children with AST to perform specific surgical treatment and prevent recurrent infection., (© 2011 The Authors.

Background: Acute suppurative thyroiditis (AST) is a rare, life-threatening thyroid infection characterized by a tender neck mass and fever. As these features are shared with self-limited subacute thyroiditis (SAT), it is important to differentiate between the two disorders., Patient Findings: We report a case of AST in a 21-year-old woman who presented with steadily worsening throat pain for 3 weeks, a tender left neck mass, and thyrotoxicosis. She was initially given prednisone for treatment of presumed SAT but then it acutely worsened. Fine needle aspiration yielded pus on gross examination, and she required intubation and emergent surgical drainage to maintain her airway. Culture of the abscess isolated Streptococcus F and Porphyromonas, a gram-negative intracellular anaerobe not previously reported to cause AST. She improved quickly after surgery, developed transient hypothyroidism that did not require treatment with thyroid hormone, and is currently euthyroid. An abnormal piriform sinus fistula was identified on the left using an esophagram., Summary: AST may be difficult to clinically differentiate from SAT. Fine needle aspiration revealing pus, culture yielding bacteria or fungi, abscess on ultrasonography and computed tomography, and left-sided predominance are important in the diagnosis of AST., Conclusions: AST should be considered in any patient with SAT who does not rapidly improve following institution of steroids. Further, the presence of thyrotoxicosis does not eliminate AST as an initial diagnosis.

A 52-year-old man presented with subacute thyroiditis and showed an intensely hypermetabolic thyroid lesion on (18)F-FDG PET/CT. The patient also had coexisting chronic lymphocytic thyroiditis. The lesion of subacute thyroiditis revealed an SUV(max) of 9.1 g/mL and was ill-defined, heterogeneous, markedly hypoechoic, and hypovascular on US. Biopsy demonstrated histologic findings of subacute thyroiditis, which should be included in the differential diagnosis of an intensely hypermetabolic thyroid lesion on (18)F-FDG PET/CT.

Background: Acute suppurative thyroiditis (AST) is a rare condition in children, and most children with AST usually have normal thyroid function., Objective: To report a case of thyrotoxicosis complicating AST in a child., Case Report: A 6-year-old boy with AST presented with the unusual clinical features of severe thyrotoxicosis. Two palpable masses were found to be of firm to hard consistency with tenderness without any acute inflammatory signs on the overlying skin of the thyroid gland. The diagnosis of AST was confirmed by ultrasonography and fine needle aspiration. Thyroid function tests were normal within a week after antibiotic treatment and surgical drainage., Conclusion: Transient thyrotoxicosis complicating AST is very rare in children. Awareness of this unusual complication is important to avoid inappropriate treatment of hyperthyroid disease.

We report an unusual case of acute suppurative thyroiditis associated with juvenile systemic lupus erythematosus (JSLE) onset. A 10 year-old girl presented with a painful voluminous swelling in the anterior cervical region with fever and dysphagia. She also had dysphonia, myalgia, swelling of the small joints of the hands, weight loss, and erythematous malar rash. Thyroid ultrasonography disclosed an ill-defined solid cystic area containing abundant echoes in suspension suggestive of an abscess in both lobes compatible with suppurative bacterial thyroiditis. Fine-needle aspiration biopsy showed a secretion with positive culture for Staphylococcus aureus. Endoscopic evaluation did not demonstrate pyriform sinus fistula. The child had no previous thyroid disease. Hormonal evaluation showed thyrotrophin (TSH) 13 microIU/ml and free thyroxine (FT4) 0.4 ng/dl. After laboratory confirmation of JSLE, high dose 'pulse' therapy was performed with methylprednisolone (30 mg/kg/day for 3 days), followed by prednisone (2 mg/kg/day). The acute thyroiditis was treated with oxacillin, metronidazole and amikacin which ameliorated the symptoms of infection followed by normalization of thyroid function with levothyroxine. In spite of the known association between autoimmune diseases and thyroid disorders, the coexistence of suppurative thyroiditis and JSLE is rare, generally occurring during the course of lupus and not at diagnosis.

Acute suppurative thyroiditis is a very uncommon disorder, most often arising in children with congenital conditions connecting the thyroid directly to the oropharynx, such as a piriform fistula or thyroglossal duct. Accordingly, the most common causative agents are those which can colonize the oral mucosa and spread to the thyroid contiguously, such as Streptococcus species, Staphylococcus species and anerobes. In adults, a hematogenous spread to a pre-existing altered thyroid gland is often the postulated pathogenetic mechanism, and it is exceedingly rare in the United States. We report the case of an 81-yr-old woman with acute suppurative thyroiditis secondary to Escherichia coli (E. coli) infection. The patient presented with fevers, chills, dysuria and recent painful neck swelling. Thyroid ultrasound and neck computed tomography revealed a multinodular goiter and an intra-thyroid abscess. An otolaryngology evaluation and barium swallow failed to show a piriform fistula. Thyroid hormone levels were consistent with hyperthyroidism. Urine cultures were positive for E. coli. The patient subsequently developed a clinical picture consistent with severe thyrotoxicosis, which rapidly resolved after medical treatment, appropriate antibiotics and surgical drainage of the thyroid. Abscess material also grew E. coli. Thus, acute suppurative thyroiditis secondary to sepsis can complicate an otherwise asymptomatic multinodular goiter and should be promptly treated with broad-spectrum antibiotics and/or surgical drainage to avoid serious consequences, including severe thyrotoxicosis.

Aim: To present a rare case of actinomycotic suppurative thyroiditis in an infant with provision of the etiology, pathogenesis, clinical findings and treatment of this rare disease., Design: A report of an 18-month-old female infant who presented with fever, erythema, induration and tenderness of the neck. The patient had the diagnosis of acute suppurative thyroiditis after a series of laboratory evaluation., Result: She was treated successfully with surgical debridement and intravenous penicillin G., Conclusion: Although rare, Actinomyces spp. should be considered in the etiology of acute suppurative thyroiditis. Because of its fastidious nature the probability of positive culture is low, thus, the microbiology laboratory should be called in advance to make preparations before culture and transport.

A case of thyrotoxicosis caused by acute suppurative thyroiditis after repeated fine-needle aspiration (FNA) is described. A 39-year-old woman with atopic dermatitis showed rapid enlargement of a left thyroid cyst after a third FNA. She had a high fever, painful swelling of the left thyroid, and elevated thyroid hormone levels. Ultrasonography revealed abscess formation in the left thyroid cyst. The cytologic examination of an FNA specimen showed abundant neutrophils, and culture of the aspirate yielded Staphylococcus aureus. Because antibiotic treatment for 1 month failed to improve the inflammatory findings, the patient subsequently underwent left thyroid lobectomy, which resulted in the normalization of thyroid function and the resolution of inflammation. Thyroid infection had possibly been induced by needle-track seeding, because atopic skin favors colonization by S. aureus because of local immunologic deficiency. FNA is a useful and safe technique for aspirating fluid from thyroid cysts, but special care is required in patients with atopic dermatatis to avoid bacterial infection.

Objectives: To investigate the management of children with life-threatening airway obstruction from large mediastinal masses., Methods: Review of the medical records of children with mediastinal masses and severe airway obstruction who were admitted to a multidisciplinary pediatric intensive care unit., Results: Eight patients with 12 life-threatening events were identified. Five events (in 4 patients) occurred before hospital admission, and 3 patients had more than 1 choking episode. Five patients underwent cardiorespiratory resuscitation (2 before admission), and 2 underwent emergency endotracheal intubation because of severe airway obstruction; the eighth patient could not be weaned off the ventilator until the mediastinal mass was resected. Median time from appearance of the initial symptoms to diagnosis was 8.5 days, and median time from the onset of alarming signs to admission was 2 days., Conclusions: Severe airway obstruction in children with an anterior mediastinal mass is not rare and can lead to complete obstruction, requiring cardiorespiratory resuscitation. Physician awareness and preparedness for respiratory complications are essential for proper management of children with mediastinal masses.

This review describes the microbiology, diagnosis and management of suppurative thyroiditis (ST). Staphylococcus aureus, Streptococcus pyogenes, Streptococcus epidermidis, and Streptococcus pneumoniae, are the predominant aerobic isolates. The most common anaerobic bacteria are Gram-negative bacilli and Peptostreptococcus spp. Agents that are rarely recovered include Klebsiella spp., Haemophilus influenzae, Streptococcus viridans, Salmonella spp., Enterobacteriaceae, Mycobacterium tuberculosis, atypical mycobacteria, Aspergillus spp., Coccidioides immitis, Candida spp., Treponema pallidum, and Echinococcus spp. Viruses have been associated with subacute thyroiditis, and include measles, mumps, influenza, enterovirus Epstein-barr, adenovirus, echovirus, and St Louis encephalitis. Therapy includes administration of antibiotics effective against the causative pathogen(s). Proper selection of therapy can be guided by culture of the lesion. Surgical drainage may be necessary in case of suppuration.

A young black Jordanian lady who has type one diabetes, chronic diabetic complication and ischemic heart disease, presented with a picture of diabetic keto-acidosis, precipitated by an acute neck swelling. This was suggestive of acute suppurative thyroiditis with abscess formation causing compressive symptoms. This unfortunate patient had an eventful course despite aggressive treatment by antibiotics and surgery and then succumbed of an acute cardiac event. The operative tissue biopsy revealed an abscess in an infarcted papillary thyroid cancer. We believe this is a rare presentation of such an association with a fatal outcome.

We report a case of tuberculous thyroiditis in a woman with Behçet's syndrome. The initial physical examination in May 1998 revealed multiple soft, nontender, mobile lymph nodes, each measuring less than 1 cm, in the left lower internal jugular chain. Sonography performed in February 2000 showed multiple small (< 1 cm), oval lymph nodes, each with an intact fatty hilum, in the left lower internal jugular chain; the thyroid gland appeared normal. Follow-up sonography 6 months later showed multifocal, heterogeneous, hypoechoic lesions with ill-defined margins in both lobes of the thyroid and several small, oval lymph nodes, each with an intact fatty hilum, in the left lower internal jugular chain. Fine-needle aspiration was performed on the largest thyroid lesion, and cytologic analysis of the aspirate revealed a small number of epithelioid histiocytes in a necrotic background, which was suggestive of tuberculosis. Follow-up sonography after 3 months of antituberculosis chemotherapy showed that the thyroid lesions had resolved., (Copyright 2002 Wiley Periodicals, Inc. J Clin Ultrasound 30:184-188, 2002; DOI 10.1002/jcu.10041)

We have experienced five cases of piriform sinus fistula for the last 10 years. It is a relatively rare disease, and partly because of poor understanding of the disease, in one case infection had repeatedly recurred without being adequately treated for over 20 years, and in most cases there was a long time lapse before the diagnosis. In another case, it was difficult to image the fistula with contrast medium and fistulectomy was performed without identifying it on imaging. We have applied various devices to those cases where imaging of fistula was difficult, and achieved complete resection of fistula and have not observed recurrences of infection after resection.

An unusual case of acute purulent thyroiditis in a 45-year-old man forming a large abscess in the left lobe of the thyroid gland is described. It perforated the capsule at the posterior wall of the thyroid, causing extensive retropharyngeal and retrotracheal abscesses. The patient was treated with broad-spectrum antibiotics and surgical excision of the infected tissues. He has remained well one year after the operation.

Suppurative thyroiditis is rare, and the major pathogens are Staphylococcus and Streptococcus species. We present a case caused by Acinetobacter baumanii, which has never before been reported. We review another 191 cases from the English-language literature (1980 to April 1997) and make a comparison with a review of 224 cases (1900-1980). As the numbers of immunocompromised patients increase, cases of suppurative thyroiditis are increasing. Pneumocystis carinii has become an important pathogen. Most patients (83.1%) with bacterial infections were euthyroid, whereas those with fungal or mycobacterial infections tended to be hypothyroid (62.5%) and hyperthyroid (50%), respectively.

A case of Candida abscess of the thyroid in a patient with acute lymphoblastic leukemia is described. The patient developed this rare complication after treatment with steroids and combination chemotherapy, during therapy with broad spectrum antibiotics for febrile neutropenia. Prior to the thyroiditis the patient had pulmonary aspergillosis. The abscess developed during treatment with high dose Amphotericin B. Unlike previous cases, the Candida was isolated to the thyroid, with no evidence of Candidemia or Candida infection in other sites.

Background: Acute suppurative thyroiditis is an increasingly rare entity, accounting for less than 0.1% of thyroid surgery. This is the first report in the literature of acute thyroiditis causing a unilateral reversible vocal cord paralysis., Methods: A 41-year-old woman was initially seen with a unilateral vocal cord paralysis resulting from acute suppurative thyroiditis., Results: The vocal cord paralysis resolved following surgical drainage of the thyroid abscess and treatment with intravenous antibiotics., Conclusions: We present this case to emphasize the need for a complete and thorough head and neck exam including preoperative documentation of vocal cord mobility.

Acute suppurative thyroiditis is an acute disease of the thyroid gland. In this paper the authors report a case of acute suppurative thyroiditis complicated by abscessual evolution in an addict patient study with ultra-sonography and treated with fine needle aspiration and antibiotic therapy. The patient reached our observation for a swelling of the neck. Ultrasonography showed diffuse hypoechogenicity in both thyroid lobes and mixed nodule with hyperechoic trabeculas inside. This nodule underwent fine needle aspiration (FNA) for cytologic and cultural evaluation. Diagnosis was acute suppurative thyroiditis. Ultrasonography presented features similar to other thyroid pathology (sub-acute thyroiditis, haemorrhagic cyst, thyroid lymphoma and anaplastic carcinoma). In our case none of the ultrasonographic features were diagnostic except hyperechoic trabeculas inside. Ultrasonographic features of acute suppurative thyroiditis are very rare in the literature. Ultrasonography and fine needle aspiration are the only methods that confirm this diagnosis.

We report a 41 years old man admitted with a tender goiter, fever, thyrotoxic manifestations and atrial fibrillation. Laboratory confirmed the diagnosis of subacute thyroiditis and treatment with aspirin and propranolol was started, obtaining a rapid relief of symptoms and normalization of heart rate. On the tenth day after admission, severe dysphagia, dysphonia, irritative cough and further enlargement of the neck mass developed. Fine needle aspiration of the mass and thyroid ultrasound lead to the diagnosis of a thyroidal abscess, which was surgically excised, draining 250 ml of purulent material. Cultures were positive for Staphylococcus aureus. Patient was treated during 21 with cloxacilyn and discharged with normal thyroid function. Long term follow up has been uneventful.

From 1969 to 1990, 15 children with acute suppurative thyroiditis (AST) were diagnosed in our hospital. Their clinical, laboratory and radiologic findings were reviewed. The characteristic features were as follows: 1) Males to female ratio was 1.5:1. 2) The ages at diagnosis ranged from 3 to 14 years, with a mean age of 6 years. 3) A painful, tender mass in the anterior neck was detected in all cases and fever was detected in 10 cases (67%). 4) The left lobe of the thyroid was affected in 11 cases (73%), whereas the right lobe was affected in the remaining 4 cases. No cases was bilateral. 5) Five cases (33%) were found to be recurrent. 6) Eight pathogenic organisms were identified on culture from 7 cases; among them 3 were due to anaerobic pathogen. 7) Leukocytosis was increased and acute-phase reactant tests were positive in most cases. 8) Thyroid function was found to be normal in all 9 cases examined. 9) Radiologic studies, which included radionuclide thyroid scan, ultrasonography, computed tomography and barium esophagogram, were very helpful for the diagnosis of AST. 10) A barium esophagogram was performed in 9 cases and a fistula originating from the pyriform sinus was found in 4 cases (44%). 11) Three cases (20%) had the complete removal of the fistula as a permanent cure. This report summarizes the clinical features of 15 children with acute suppurative thyroiditis diagnosed in our hospital during the past twenty years.

A case of suppurative thyroiditis occurring in a 72-year-old woman is reported. The clinical history of this woman, treated by tianeptine for mild exogenous affective disorder and by conventional insulin therapy for long-standing insulin-dependent diabetes, was remarkable for the pseudotumoral signs which led to the simultaneous diagnosis of hypothyroidism due to Hashimoto's thyroiditis and of mycobacterium avium intracellulare suppurative thyroiditis. To our knowledge, this is the second reported case of mycobacterium avium intracellulare thyroiditis. This case is also exemplary, given its occurrence in the absence of severe immunodepression, setting apart the mild impact on the immune system of affective disorder and of long duration's insulin-dependent diabetes.

Infective thyroiditis is an uncommon condition, and fungal infection of the thyroid gland is rare. We present a case of Candida thyroiditis in a patient with leukaemia and review the three previous reports of this entity in the world's literature. We conclude that Candida thyroiditis should be considered in immunosuppressed patients with known infection who develop fever and neck pain, that gallium scanning may help localise the infection to the thyroid gland; that fine needle aspiration is a useful diagnostic test, and that thyroid dysfunction is common with Candida thyroiditis.
