Background: X-linked adrenal hypoplasia congenita (AHC) is a rare disorder, often manifesting as primary adrenal insufficiency (PAI) and hypogonadotropic hypogonadism (HH), and caused by variants of NR0B1, most of which are frame-shifting variants, and few splice-site variants., Methods and Results: Here, a novel splice-site variant of NR0B1 (NM_000475.4), c.1169-2A>T (patient 1), and a stop-loss variant of NR0B1 c.1411T>C (patient 2) are described in this study. We perform minigene assays for the splice-site variant (c.1169-2A>T) and determine that the variant causes exon 2 skipping. Moreover, the defect of NR0B1 protein may bring about the severe phenotype of the patient. Through 8 years of follow-up, we compare the CT images from 8 years ago with the latest image, and observe the CT image change of adrenal in patient 2 (from the increased thickness of adrenal to adrenal atrophy)., Conclusion: X-linked adrenal hypoplasia congenita is produced by variants of NR0B1. We report a case that presents a novel splice-site variant, which has been verified that it could lead to the exon 2 skipping in the RNA splicing progress. Moreover, we report the adrenal CT image change of patient 2, which has never been referred to before, and expand the spectrum of X-linked AHC characteristics., (© 2023 The Authors.

Background: Clinical findings of glucocorticoid-deficient hypoadrenocorticism (GDH) can overlap with other diseases, presenting a diagnostic challenge., Objectives: Describe clinicopathologic and ultrasonographic features of dogs with GDH and those suspected of having GDH that had the disease ruled out., Animals: Six hundred twenty-three dogs., Methods: Records from dogs with suspected GDH between 2003 and 2018 were reviewed. Dogs with hyperkalemia or hyponatremia were excluded. Dogs were categorized as controls when the resting serum cortisol or post-ACTH cortisol concentration were > 2 μg/dL. Clinicopathologic and ultrasonographic features were compared between groups. The optimal cut-point, area under the receiver operating characteristic curve (AUC), sensitivity, and specificity were calculated for individual features used to detect GDH., Results: Dogs were categorized as GDH (n = 29) or controls (n = 594). Lymphocyte count (>1750 cells/L; sensitivity, 96.6%; 95% confidence interval [CI], 82.8%-99.8%; specificity, 60.3%; 95% CI, 56.3%-64.1%; AUC, 0.828; 95% CI, 0.762-0.894) and albumin/globulin ratio (<1.081; sensitivity, 86.2%; 95% CI, 69.4%-94.5%; specificity, 78.8%; 95% CI, 75.3%-81.9%; AUC, 0.886; 95% CI, 0.827-0.944) had the highest discriminatory power between groups. Left adrenal gland width <0.39 cm was 80% (95% CI, 58.4%-91.9%) sensitive and 82.4% (95% CI, 74.2-88.4) specific for GDH. Serum cobalamin concentrations and ultrasonographic abnormalities of the GI tract were not different between groups., Conclusion and Clinical Importance: No single variable could be used to confidently rule out GDH and obviate the need for cortisol testing in dogs with a clinical presentation consistent with GDH., (© 2022 The Authors.

IMAGe syndrome is a rare congenital disorder, presenting with intrauterine growth restriction, metaphyseal dysplasia, adrenal hypoplasia congenita and genital anomalies (in males). So far only 17 individuals have been diagnosed molecularly with IMAGe syndrome, this patient is the first case of an individual diagnosed with IMAGe and concurrent rhabdomyosarcoma. The patient was born at 30 weeks' gestation and received treatment for hyponatremia and hyperkalemia. At 4 9/12 years of age the patient showed a painless, non-mobile mass on the left thigh. In the biopsy performed a sarcoma weave with solid, nest-like growth, with characteristics of rhabdomyosarcoma was identified. The family history and physical examination indicated IMAGe syndrome so genetic testing was requested. A whole exome sequencing procedure with use of SureSelectXT Human ALL Exon V7, confirmed a single nucleotide variant NM&#95;000076.2(CDKN1C):c.820G>A (p.Asp274Asn); identifying a missense mutation in the imprinted gene CDKN1C associated with IMAGe syndrome. Although tumours associated with CDKN1C are rare, deregulation of imprinted genes is increasingly being recognised as a mechanism of tumorigenesis in cancer; chromosomal region 11p15.5 contains a cluster of imprinted genes. This same region is the most consistent site of allele loss in rhabdomyosarcoma and is the same region altered in both IMAGe and Beckwith-Wiedemann syndrome. Molecular studies have found genetic changes in the 11p15 region in a variety of embryonal tumours like Wilms tumours which are commonly developed in Beckwith-Wiedemann syndrome and embryonal rhabdomyosarcoma. Through this case we aim to present the possibility of oncogenesis in patients with IMAGe syndrome, specifically rhabdomyosarcoma., Competing Interests: Declarations of Competing Interest None., (Copyright © 2021.

Background: Rathke's cleft cysts are benign cystic lesions of the sellar region, which may cause headache, pituitary deficiencies and visual disturbances from mass effect. Their management is not standardized yet. This study is about establishing a consensus for medical care of RCC., Material and Methods: We performed a retrospective observational study of all patients that were diagnosed or followed for RCC between 2008 and 2018 (11 years), in the neurosurgical and the adult endocrine departments of our institution. The study's average time length of follow-up is 72.9 months (from 2 to 385 months)., Results: The 57 included patients were divided into 2 groups: group A, which included 39 patients that were conservatively managed and group B, which included 18 surgically treated patients. Group A showed either an improvement or a spontaneous resolution of headaches in 56.1% of the cases (P<0.01); a resolution of hyperprolactinemia in 70% of the cases (P=0.21); and of hypogonadism, ACTH deficiency, growth hormone deficiency in 100% of the cases. There was no spontaneous improvement of visual disturbances (P<0.01) or diabetes insipidus (P=0.29) during follow-up. Regarding group B, surgery allowed improvement or complete resolution of headaches in 60% of the cases; visual troubles in 100% of the cases (P<0.01); and hyperprolactinemia in 100% of the cases. Pituitary deficiencies were not improved by surgery., Conclusions: This study offers guidance in decision-making regarding the management of RCC patients. Surgery is particularly suitable for treating visual disturbances caused by RCC. Regular follow-up is more appropriate than surgery concerning headaches, hyperprolactinemia, endocrine disruptions and diabetes insipidus., (Copyright © 2021 Elsevier Masson SAS.

Disseminated histoplasmosis, with the adrenal glands as being the only site of demonstrable disease in an immunocompetent adult, is a rare infection leading to adrenal insufficiency. This disease carries high mortality when unrecognised. We describe the first reported case of adrenal histoplasmosis in the Philippines in a 72-year-old immunocompetent, Filipino man who presented with a 3-month history of intermittent flank pain, weight loss and generalised weakness. His imaging demonstrated bilateral adrenal masses on ultrasonography and contrast-enhanced CT scan. The initial impression was adrenal cancer, however, fine-needle aspiration cytology revealed the presence of yeast cells and blood culture grew Histoplasma capsulatum The diagnosis of the case represents a diagnostic challenge in immunocompetent individuals because they manifest with non-specific symptoms. A heightened suspicion is therefore needed to prevent significant morbidity and mortality., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2020.

Allgrove syndrome is a rare autosomal recessive syndrome of unknown prevalence. The first case of Allgrove syndrome was reported in 1978 by Allgrove. It is characterized by triad of achalasia, alacrima and adrenal hypoplasia. There are also associated autonomic and neurological manifestations. We report the case of a 7 years old boy being treated for achalasia cardia, presented with fits and altered sensorium which on further investigations was found to be due to adrenal insensitivity (Raised ACTH level, low Cortisol level, and normal Aldosterone and Renin ratio). He also had undiagnosed alacrima since birth, mild degree of hearing loss and autonomic instability in the form of episodic hypertension.

Rathke's cleft cysts (RCCs) are non-neoplastic, sellar or suprasellar epithelium-lined cysts originating from Rathke's pouch in the pituitary gland. Patients with RCCs are usually asymptomatic, but some have only been identified when symptoms manifested in middle age. The characteristics of these patients during childhood or adolescence remains unknown. We describe an 18-year-old girl who had occasionally suffered from malicious fatigue in the morning since her early teens. Brain magnetic resonance imaging (MRI) revealed T1 hyperintense/T2 hypointense signals between the anterior and posterior pituitary glands, indicating the presence of RCC. Based on an authentic endocrinological evaluation, her adrenal function seemed normal; nevertheless, her serum cortisol level strangely dropped around noon. Furthermore, daily supplementation of oral hydrocortisone bizarrely suppressed ACTH secretion to below the detection range in the morning. These data appeared compatible with the presence of central adrenal dysfunction. We also review the literature for previously reported cases. In conclusion, the symptoms and endocrinological data for dysfunction of the hypothalamic pituitary system might be non-specific and vary among patients, especially in teenagers. Brain MRI and daily cortisol profiling in blood are key to obtaining a diagnosis of an impaired hypothalamic adrenal function due to RCC.

Background: Sepsis is a syndrome of life-threatening organ dysfunction caused by a dysregulated host response to infection. It can have devastating consequences, including bilateral adrenal hemorrhage, particularly in patients at high thrombotic risk, such as those with antiphospholipid syndrome and those on long-term anticoagulation., Case Presentation: A 49-year-old white woman re-presented to hospital with a history suggestive of sepsis. She had a medical background of primary antiphospholipid syndrome on lifelong warfarin. Ten days prior to this presentation, she had been hospitalized following Escherichia coli bacteremia, commenced on intravenous antibiotics, and discharged 2 days later with a prescribed 5-day course of oral amoxicillin. On readmission, she had ongoing fever, myalgia, malaise, and hypotension. Investigations revealed anemia with thrombocytopenia, hyponatremia, and acute-on-chronic kidney injury. Despite treatment for urosepsis, she became tachypneic, clammy, light-headed, drowsy, and hypothermic. Computed tomography revealed bilateral adrenal hemorrhage, and biochemical examination confirmed hypoadrenalism. Following discharge, she had persistent renal and hepatic injury lasting 3 months., Conclusions: Early identification, intensive monitoring, and aggressive support may reduce the acquired thrombotic risk and avoid potentially life-threatening outcomes of sepsis.

Background/aims: Autoimmune hypophysitis (AH) is a rare inflammatory disease of the pituitary gland causing varying degrees of hypopituitarism and/or sellar compression. Cranial MRI remains the best noninvasive tool to diagnose AH, although a diagnosis of certainty requires pituitary biopsy. The objective of this study was to assess the utility of detecting pituitary antibodies for the diagnosis of AH., Methods: A 15-year-old female with Turner syndrome (TS), hypothyroidism, and ovarian failure presented acutely with hypocortisolism. Laboratory studies revealed secondary adrenal insufficiency. MRI showed a hypotrophic pituitary gland and loss of the posterior pituitary bright spot. To establish an autoimmune basis for the adrenal insufficiency, serum was analyzed by double indirect immunofluorescence for the presence of pituitary autoantibodies., Results: The patient's serum contained autoantibodies that recognized 36% of the adrenocorticotropic hormone-secreting cells, suggesting that these adenohypophyseal cells were targeted by autoimmunity. The serum contained antibodies that identified the majority of the gonadotropin-secreting cells (FSH 77%, LH 65%). No recognition of GH-, prolactin-, and TSH-secreting cells was found. Preabsorption experiments showed that antigenic targets of autoantibodies were not anterior pituitary hormones themselves., Conclusion: Demonstration of circulating pituitary antibodies expands the diagnostic options for AH. In this adolescent with TS, positive and cell-specific pituitary antibodies suggested that AH was the cause of her secondary adrenal insufficiency., (© 2016 S. Karger AG, Basel.)

Primary adrenal lymphoma is an extremely rare condition. We describe a case of bilateral adrenal lymphoma in a man aged 55 years who was admitted to our hospital. He had a 3-month history of left flank pain, nausea and vomiting with weight loss. A CT scan at a private hospital revealed bilateral large adrenal masses; the patient was referred to our centre based on these findings. He was evaluated for pheochromocytoma by an endocrinology team; however, all findings were negative. In addition, a cosyntropin stimulation test indicated adrenal insufficiency. A Trucut biopsy of the adrenal gland revealed diffuse large B-cell lymphoma of the adrenal glands, and the patient responded extremely well to chemotherapy., Competing Interests: Conflicts of Interest: None declared., (2016 BMJ Publishing Group Ltd.)

We report a young woman with the clinical picture of Allgrove syndrome in whom neurological symptoms are prominent. It usually presents in the first decade of life with a deficiency of tears, recurrent vomiting and dysphagia due to achalasia, severe hypoglycemic seizures and shock due to adrenal insufficiency. Neurological symptoms such as hyperreflexia, dysarthria, hypernasal speech, ataxia, sensory impairment, muscle weakness, and mental retardation are extremely slow to develop and manifest at a later age. Diagnosis was based on clinical presentation and laboratory findings. She is the first patient from the Czech Republic with genetic confirmation of Allgrove syndrome. This patient is one of about 100 cases described in the literature and one of the few patients with all the main typical clinical features.

Tuberculosis (TB) remains one of the leading infectious causes of death throughout the world. Extrapulmonary forms, namely adrenalitis and prostatitis, are rare presentations of TB and pose a difficult diagnostic challenge, given their non-specific manifestations. The authors present a case of a 42-year-old man with long-standing symptoms of fatigue, anorexia, weight loss, nightly fever and sudoresis. He also suffered from sporadic vomiting and episodic hypotension, and had skin hyperpigmentation, as well as frequent urination, perineal discomfort and pain at ejaculation. Laboratory investigation confirmed primary adrenal failure. On CT scan there were two hypodense right adrenal nodules and bilateral lung condensations with a tree-in-bud pattern. Another hypodense nodule was seen in the prostate. TB was diagnosed by isolatingMycobacterium tuberculosisfollowing cultures of bronchoalveolar lavage, bronchial secretions, urine and ejaculate. Antibacillary treatment resolved the infectious lesions but the patient remained on corticosteroid replacement therapy for ongoing adrenal failure., (2016 BMJ Publishing Group Ltd.)

Allgrove syndrome is a rare genetic disorder typically manifested by alacrima, achalasia, and adrenal insufficiency, and is one of the rare causes of achalasia in infants. While the gold standard for achalasia treatment in adults is an esophageal myotomy with fundoplication, a standard treatment for infantile achalasia remains undetermined due to the low number of reported cases and rarity of the disease in this age group. We report a 7.7 kg infant with achalasia secondary to Allgrove syndrome who was successfully treated by Heller myotomy and simultaneous Toupet fundoplication. This case represents one of the smallest patients to ever be treated for achalasia and highlights the role that primary surgical therapy may have for the infantile variant of the disease.

A 64-year-old woman with history of lung cancer and left adrenal gland metastasis was referred for FDG PET/CT to assess the response to target therapy and local radiotherapy treatment. In addition to bilateral adrenal gland FDG uptake lesions, the PET/CT also showed focal FDG uptake in pituitary gland with standardized uptake value of 3.9. Adrenocorticotropic hormone serum level was 439 pg/mL (normal <46 pg/mL), and serum cortisol level was 6 μg/dL (normal range, 5-25 μg/dL). The image and serum test results suggested the diagnosis of lung cancer, with bilateral adrenal metastases causing adrenal cortical insufficiency with secondary pituitary gland hyperplasia.

We report a rare case of bilateral hemorrhage of adrenal glands diagnosed in a 61-year-old female. The case presented with classic clinical findings and typical imaging features.

The adrenal glands of 30 dogs with primary adrenal insufficiency (hypoadrenocorticism) were measured ultrasonographically and compared with those of 14 healthy dogs and those of 10 dogs with diseases mimicking hypoadrenocorticism. Thickness and length of the adrenals were measured on abdominal ultrasonography and the results for each group were compared. Dogs with primary hypoadrenocorticism had significantly thinner adrenals compared with the other two groups, and their left adrenal glands were also significantly shorter than those of healthy dogs. Adrenal ultrasonography may be of diagnostic value in dogs with clinical signs suggestive of primary hypoadrenocorticism, as a left adrenal gland measuring less than 3.2 mm in thickness is strongly suggestive of the disease.

We investigated the postnatal pattern of changes in adrenal size in very low-birth-weight (VLBW) infants and its relation to late-onset glucocorticoid-responsive circulatory collapse (LGCC) that may be associated with adrenal insufficiency. In 36 VLBW infants born at <33 weeks' gestation, ultrasound examinations of postnatal changes in adrenal size during the first 3 weeks of life were performed. VLBW infants were classified into three groups: group A (N = 6), the actual adrenal area was greater than or equal to the predicted value at birth and unchanged at 3 weeks; group B (N = 24), the actual adrenal area was greater than or equal to the predicted value and decreased at 3 weeks; and group C (N = 6), the actual adrenal area was less than the predicted value and unchanged at 3 weeks. Five infants developed LGCC, and all five were in group A. These observations suggest that the life of the adrenal fetal zone might be extended beyond 3 weeks after birth in some VLBW infants and that prolonged fetal zone activity might correlate with LGCC. On the other hand, adrenal maturation might have already occurred at birth in some VLBW infants. Sonographic evaluation of adrenal size may enable prediction of subsequent LGCC in VLBW infants., (Thieme Medical Publishers.)

The study was aimed at bettering therapeutic outcomes for patients suffering from adrenal-aetiology arterial hypertension, with the objective deemed attainable at the expense of revealing and removing the underlying causes potentially contributing to unfavourable results obtained after roentgenoendovascular ablation of the adrenal glands. We retrospectively examined the medical records of 49 patients having undergone hospital treatment within the time frame from 1992 to 2007 for recurrent arterial hypertension poorly controlled by previously endured roentgenoendovascular (REV) interventions. The identified causes contributing heavily to poor clinical outcomes obtained after the REV-ablation procedures appeared to have been as follows: renal parenchymatous diseases in 20 patients having a long history of arterial hypertension with evidence ofnephroangiosclerosis; insufficient devitalisation of the adrenal glands in a further 19 patients; a pheochromocytoma of the right adrenal gland in only one instance; and newly onset renovascular hypertension in the remaining nine subjects. It was determined that poor therapeutic outcomes had primarily been caused by overestimating the indications for performing REV ablation of the adrenal glands, being seemingly wanton as a corrective measure to have been taken in the presence of inflammatory diseases of the renal parenchyma and secondary hyperplasia of the adrenal gland, with the second-in-order contributory cause appearing to be insufficient devitalisation of the adrenal glands afflicted by hyperplasia and/or aldosteroma. The development of renal artery stenosis in the remote period after REV interventions may also be responsible for a relapse of arterial hypertension, which is quite often the case.

The large hyperaemic foetal adrenal gland is vulnerable to vascular damage. This may occur in the neonatal period as a consequence of difficult labour, or its aetiology may not be apparent. The spectrum of presentation is considerable, ranging from asymptomatic to severe life-threatening intra-abdominal haemorrhage. The presentation of adrenal insufficiency may be delayed but the regenerative capacity of the adrenal is great, and most adrenal haemorrhage is not associated with significantly impaired function. Some reports showed that cholestatic hepatopathy with congenital hypopituitarism reversed by hydrocortisone treatment is considered in the context of the endocrine syndrome, probably as a consequence of the adrenal failure. We describe a case of bilateral adrenal haemorrhage with hepatitis syndrome and persistent hypoglycaemia in a newborn male with striking features of neonatal cholestasis and adrenal crisis.

Background: Female adrenal insufficiency implicates reduced production of the adrenal androgen precursor dehydroepiandrosterone (DHEA) and low androgen levels. Oral DHEA restores androgen deficit but the clinical implications and safety of substitution therapy is uncertain. A putative DHEA receptor in vascular endothelium has been described and in vitro studies have shown involvement of DHEA in NO dependent pathways., Aim: To evaluate effects of DHEA substitution on cardiovascular parameters., Design: Six months randomized, double-blind, placebo-controlled crossover study. Treatment consisted of DHEA 50-mg or placebo. Each treatment period was followed by a 2-month washout period., Material and Methods: Ten females with documented adrenal failure were included. Androgen levels were measured. Cardiovascular evaluation was performed before and after every treatment period. Two patients left the study because of skin side effects and anxiety, respectively. All patients had low circulating androgens baseline and normal range androgens during DHEA treatment. We examined patients with noninvasive endothelial cell function, magnetic resonance imaging (MRI)-based cardiac output, echocardiography, ambulatory 24-h blood pressure and maximal oxygen consumption., Results: DHEA treatment normalized androgen status to levels seen in healthy women. DHEA and placebo treatment had no effect on echocardiographic parameters of myocardial dimensions or systolic and diastolic function, noninvasive endothelial cell function at the level of the brachial artery, 24-h blood pressure and heart rate, cardiac output and maximal oxygen consumption during exercise cycle testing. Remarkably, all participants had evidence of concentric left ventricular remodelling by echocardiography., Conclusion: Restoration of physiological androgen levels using 6 months of DHEA replacement in this pilot study did not affect cardiovascular parameters and endothelial function in female adrenal insufficiency.

Objective: Mutations in the gene coding for the orphan nuclear receptor DAX1 cause X-linked adrenal hypoplasia congenita (AHC). Affected boys usually present with primary adrenal failure in early infancy or childhood. Impaired sexual development due to hypogonadotropic hypogonadism becomes manifest at the time of puberty. Moreover, evidence from Dax1 knockout mice and a limited number of patients with AHC, suggests that mutations in DAX1 may directly cause abnormalities in spermatogenesis. The aim of this study was to characterize clinically and genetically five patients with AHC., Design: DNA sequencing analysis, endocrine testing, testicular ultrasound and semen analysis with 1-year follow-up after gonadotropin treatment., Methods: We report on five men with classic AHC manifestations. Genomic DNA was extracted from patients' peripheral blood leukocytes and the coding region, splice sites, and promoter (-240 bp) region of DAX1 were directly sequenced., Results: Three known and two novel mutations were detected in the DAX1 coding sequence in these patients. Semen analysis was performed in four of the five patients and showed azoospermia. Twelve-month treatment with gonadotropins did not restore fertility in these patients. All patients showed a normal testicular Doppler ultrasound, in contrast with that observed in Dax1-deficient mice, which display abnormalities in the rete testis., Conclusions: These cases further expand the number of DAX1 mutations reported in the literature, as well as our clinical knowledge of this rare disease.

We describe a 69-year-old woman with bilateral adrenal hemorrhage complicated with antiphospholipid syndrome (APS). She was hospitalized with nausea and vomiting in September 2003. Laboratory data demonstrated hyponatremia, hypoglycemia and prolongation of activated partial thromboplastin time (aPTT). Abdominal computed tomography showed bilateral adrenal enlargement. In October 2003, she demonstrated altered mental status with progressive hyponatremia, a high level of ACTH, and a low level of serum cortisol. She also showed thrombocytopenia, anti-cardiolipin IgG antibody, anti-beta2GPI antibody, and lupus anticoagulants. After four months, anti-cardiolipin IgG antibody was still positive. Based on these findings, she was diagnosed as having APS complicated with adrenal insufficiency due to hemorrhagic infarction. After treatment with corticosteroid, a low dose of aspirin and normal saline infusion, her condition quickly improved. Platelet counts and aPTT were also normalized. To our knowledge, this is the second Japanese case of APS complicated with bilateral adrenal hemorrhage. APS should be considered an important underlying cause of adrenal insufficiency.

Acute adrenal failure is a potentially fatal condition if overlooked. Occasionally, acute adrenal insufficiency may ensue from bilateral adrenal haemorrhage in patients with known antiphospholipid syndrome (APS). APS is characterized by recurrent arterial and venous thrombosis, pregnancy complications and detection of autoantibodies to phospholipids. This syndrome may be associated with non-organ specific diseases (e.g. connective tissue disorders) or with malignancies, but it may also appear in isolated form (primary APS). In a very few cases the heralding manifestation is given by adrenal failure. We report here a 63-year-old man presenting with acute adrenal insufficiency as the opening clinical manifestation of an APS. We also carried out a computer-aided search of the literature to identify all cases of primary adrenal failure as the first-recognized expression of a primary APS, a condition that not so infrequently may be tackled by endocrinologists. 20 patients fulfilled the inclusion criteria. The great majority of them were males (75%) with a mean age of 42 years. Abdominal pain was present in 14 patients, followed by fever (13 patients) and hypotension (12 patients). The main morphological findings by computed tomography or magnetic resonance were consistent with bilateral adrenal haemorrhage in 11 patients. Lupus anticoagulant was present in all of the 19 tested patients. Our observations emphasize the importance in the assessment of clotting times, and possibly of antiphospholipid antibodies, in all patients with diagnosis of rapidly progressive adrenal failure and concurrent abdominal pain.

The authors report a case of a 56-year-old Thai woman with a history of recurrent venous thrombosis, spontaneous abortion and Graves' disease who presented with bilateral flank pain, nausea, vomiting and low-grade fever followed by hypotension. Adrenal crisis from bilateral adrenal hemorrhage was diagnosed by a low serum cortisol level during hypotension and bilateral hyperdense oval masses in each of the adrenal glands in a computerized tomographic study. Her hemostatic and serologic profile was compatible with primary antiphospholipid syndrome. Rapid improvement was observed after the administration of intravenous hydrocortisone. She was discharged on long-term glucocorticoid replacement for her primary adrenal insufficiency as well as an anticoagulant for prevention of thrombosis. The antiphospholipid syndrome should be suspected in a patient presenting with adrenal crisis without a distinct etiology.

Acute adrenal hemorrhage (AAH) is an extremely rare disorder, especially in adults, and may be difficult to diagnose because of its nonspecific presentation. We report a case of AAH following a sepsis, resulting in persistant adrenal insufficiency contrasting with the radiologic normalisation of the adrenals on computed tomography (CT) scan imaging.

Objective: To describe a patient admitted with acute adrenocortical failure and a right adrenal mass without evidence of tuberculosis, who was ultimately diagnosed with isolated adrenal tuberculosis after postoperative histopathologic evaluation., Methods: A case report is presented, with clinical, laboratory, and imaging findings. We also discuss potential factors that may complicate the diagnosis of tuberculosis., Results: A 61-year-old man was admitted with symptoms and signs of acute adrenal crisis. The patient had an erythrocyte sedimentation rate of 30 mm in 1 hour, a negative tuberculin skin test, a 6-cm right adrenal mass, and left adrenal nodularity in conjunction with normal findings on a computed tomographic scan of the chest. He recovered dramatically after intravenous corticosteroid treatment. Investigation, including acid-fast staining and cultures for tuberculosis of all available specimens, gastroduodenoscopy and rectosigmoidoscopy, intestinal x-ray imaging, and autoantibody studies, did not disclose the diagnosis. Subsequently, bilateral adrenalectomy revealed isolated tuberculosis of the adrenal glands on histopathologic evaluation. Quadruple antituberculous therapy was initiated, and continued follow-up of the patient is scheduled., Conclusion: Our case indicates that acute or chronic adrenocortical failure can occur as a result of tuberculosis of the adrenal gland, despite the absence of clinical and laboratory evidence of tuberculosis.

We report two siblings with an IMAGe syndrome. IMAGe is a newly reported syndrome characterized by the association of intra-uterine growth retardation, metaphyseal dysplasia, congenital adrenal hypoplasia and genital anomalies. This clinical association has only been described in five unrelated males. These two additional patients (one brother and one sister) suggest an autosomal recessive inheritance although identification of new cases will give further insight into the pathogenesis. The radiologic signs of osteopenia and metaphyseal dysplasia can suggest this diagnosis in affected individuals.

We present a family with X-linked adrenal hypoplasia congenita (AHC) due to a truncation mutation in the DAX1 gene. The three patient reports demonstrate variable clinical and biochemical features at presentation. They presented with adrenal crises at 3 years, 4 weeks, and 3 weeks. Mineralocorticoid deficiency preceded glucocorticoid deficiency in patient 3 and an early ultrasound indicated normal sized adrenal tissue. Genetic analysis showed that potential female carriers were unaffected.

Survey radiographs often are obtained in dogs with primary hypoadrenocorticism in adrenal crisis as part of the routine evaluation of a critically ill dog. In this study, standardized methods of cardiac, pulmonary vasculature, and vena cava mensuration were used in 22 dogs with naturally-occurring primary hypoadrenocorticism, and the findings were compared with those in 22 breed-matched, clinically normal dogs. Most (81.8%) untreated dogs with primary hypoadrenocorticism had one or more radiographic abnormalities, including small size of the heart (45.5%), cranial lobar pulmonary artery (36.4%), caudal vena cava (54.5%), or liver (36.4%). Megaesophagus was not found in any of the dogs with hypoadrenocorticism, and therefore, compared to the other common radiographic findings, should be considered a rare finding.

The purpose of this study was to determine the value of ultrasonographic characterization of the adrenal glands in dogs with hypoadrenocorticism. Measurements of adrenal glands were obtained in six dogs with hypoadrenocorticism. The adrenal glands on both sides were shorter (range: left adrenal gland length, 10.0 to 19.7 mm; right adrenal gland length, 9.5 to 18.8 mm) and thinner (range: left adrenal gland thickness, 2.2 to 3.0 mm; right adrenal gland thickness, 2.2 to 3.4 mm) than in normal dogs (range: left adrenal gland length, 13.2 to 26.3 mm; right adrenal gland length, 12.4 to 22.6 mm; left adrenal gland thickness, 3.0 to 5.2 mm; right adrenal gland thickness, 3.1 to 6.0 mm). Statistical analysis revealed a significant reduction in size of the left adrenal gland (p less than 0.05) in dogs with hypoadrenocorticism compared to the left adrenal gland in normal dogs. The results of this study show that atrophy of the adrenal glands in dogs with hypoadrenocorticism seems to lead to an ultrasonographic-measurable reduction in size of the adrenal glands.
