A Rare Case of Giant Bilateral Adrenal Myelolipomas in a Patient With Classical Congenital Hyperplasia.

Congenital adrenal hyperplasia (CAH) is caused by genetic defects in the enzymes involved in cortisol biosynthesis in the adrenal gland and, in more than 90% of cases, due to a deficiency in the 21-hydroxylase enzyme. Classical CAH due to 21-hydroxylase deficiency is a severe form of the disease that presents with cortisol deficiency and is further categorized into salt-wasting or simple-virilizing types. Appropriate steroid replacement has been shown to effectively treat patients with classical CAH and prevent complications. Individuals who receive inadequate treatment or fail to comply with their prescribed steroid hormone regimen are susceptible to the development of adrenal myelolipomas. Myelolipomas are benign tumors composed of both adipose and hematopoietic tissues. While documented cases of adrenal myelolipomas exist in medical literature, instances of large bilateral myelolipomas remain exceedingly rare. This case report highlights a 40-year-old female patient with a known history of classical congenital adrenal hyperplasia who presented with unusually large bilateral adrenal myelolipomas. A diagnostic CT scan of the abdomen and pelvis revealed a 13.4 x 10.8 cm myelolipoma on the left adrenal gland and a 10 x 8.6 cm myelolipoma on the right adrenal gland. Prior to her presentation, the patient experienced recurrent nausea and vomiting, along with left upper quadrant pain, over five months. Hormonal assessments indicated significantly elevated serum androgen levels, suggesting inadequate management of her CAH. In this report, we present a rare case of symptomatic bilateral large adrenal myelolipomas, underscoring the significance of adhering to treatment regimens, diagnostic assessments, and management for adrenal myelolipomas in individuals diagnosed with CAH.

Nasal-Type Natural Killer/T-cell Lymphoma With Inaugural Testicular Presentation in a Young Patient.

Nasal-type natural killer/T-cell lymphoma is a rare non-Hodgkin's malignant lymphoma. A distinct clinicopathological entity associated with the Epstein-Barr virus, it typically presents with otorhinolaryngeal symptomatology. We report a rare case of a 24-year-old patient with nasal-type lymphoma with an atypical inaugural testicular presentation associated with the discovery of bilateral adrenal involvement.

Histiocytosis Presenting as Bilateral Adrenal Masses: A Case Report.

Introduction: Adrenal masses are a rare diagnosis in children, with bilateral masses even less common. At present, appearance of the mass on imaging and histology can give important clues to the diagnosis; however, there is significant overlap in 10-30% of cases and it can be difficult to distinguish benign from malignant adrenal masses. As a result, the clinical presentation remains a large part of the diagnostic process, as well as thorough endocrinology evaluation to determine if the tumor is functional versus nonfunctional. Case Presentation: We present a recent case of bilateral adrenal masses in a pediatric patient at our institution, with an unusual diagnosis of histiocytosis. Conclusion: In this case, the diagnosis was unclear, until genetic testing and pathology allowed for expedient diagnosis and targeted therapy for this patient. We hope that presenting this case will increase physician awareness of this condition and expedite diagnosis and treatment in other patients with this rare presentation.

An unusual cause of abdominal pain: spontaneous bilateral adrenal hemorrhage.

Bilateral adrenal hemorrhage (BAH) is a rare condition that can lead to acute adrenal insufficiency and death if not recognized and treated promptly. We report the case of a 30-year-old male who presented to the emergency department with acute abdominal pain, nausea, and vomiting. On emergency room admission, the first abdominal CT revealed normal adrenal glands without enlargement, but with the development of hypotension and hypoglycemia, a second CT performed four days later showed enlargement due to hemorrhage in both adrenals. The diagnosis of BAH associated with acute adrenal insufficiency was retained. Prompt treatment with intravenous and oral corticosteroids resulted in successful conservative management. We describe the clinical, biological, radiological and etiological features of this condition based on a review of the literature.

Bilateral adrenal histoplasmosis presenting as adrenal mass mimicking malignancy in an immunocompetent patient.

We report a case of a 78-year-old immunocompetent man who presented with worsening fatigue and lethargy for one month. He had also been complaining of cough and SOB for two months which had been attributed to his underlying COPD and possible pneumonia. CT showed bilateral pleural effusions, ground-glass opacities, cirrhosis, splenomegaly and bilateral adrenal masses which was highly suspicious for malignancy. After pheochromocytoma was ruled out, EUS-FNA guided biopsy was performed on the left adrenal gland. Histology was positive for yeast cells, with fungal staining (PAS) revealing narrow-based budding compatible with Histoplasma. The patient was treated with amphotericin and itraconazole. Our case is unique as he presented with hepatosplenomegaly, which is reported in less than a quarter of cases. Although typically a diagnosis in immunocompromised patients, a high index of clinical suspicion is required to diagnose disseminated histoplasmosis in an immunocompetent patient. The gold standard for diagnosis is fungal tissue culture. However results may take up to weeks. EUS-FNA guided biopsy of adrenal glands can aid in early definitive diagnosis and management.

A Case of Disseminated Histoplasmosis From California, in the Setting of Secondary Hemophagocytic Lymphohistiocytosis: A Diagnostic Challenge.

Histoplasma capsulatum is a geographically specific dimorphic fungus that can cause a spectrum of diseases. While most cases are asymptomatic pulmonary infections, in severe cases, particularly in immunocompromised patients, disseminated disease can occur. Histoplasmosis in California is limited to only a few case reports. In this article, we describe a rare case of disseminated histoplasmosis in a non-endemic region presenting with diagnostically challenging symptomatology, including altered mental status, status epilepticus, septic shock, and bilateral adrenal masses.

Adrenal venous sampling for lateralization of cortisol hypersecretion in patients with bilateral adrenal masses.

OBJECTIVE: The objective of this study was to evaluate the role of adrenal venous sampling (AVS) in guiding the management of patients with corticotropin (ACTH)-independent glucocorticoid secretory autonomy and bilateral adrenal masses. DESIGN AND PATIENTS: A cohort with 25 patients underwent AVS and surgical management. MEASUREMENTS: Cortisol was measured from the adrenal veins (AVs) and inferior vena cava (IVC). AV/IVC cortisol ratio and cortisol lateralization ratio (CLR) (dominant AV cortisol concentration divided by the nondominant AV cortisol concentration) were calculated. Posthoc receiver-operating characteristic curves were generated to determine the specificity of revised AV/IVC cortisol ratio and CLR in differentiating unilateral from bilateral disease. RESULTS: Patients underwent unilateral (n = 21) or bilateral (n = 4) adrenalectomy. The mean AV/IVC cortisol ratio for unilateral adrenalectomy was 12.1 ± 9.6 (dominant) and 4.7 ± 3.8 (contralateral) with a mean CLR of 3.6 ± 3.5. The mean AV/IVC cortisol ratio for bilateral adrenalectomy was 7.5 ± 2.1, with a mean CLR of 1.1 ± 0.6. At a mean follow-up of 22 months, one patient who underwent unilateral adrenalectomy for the predicted bilateral disease developed recurrent mild autonomous cortisol secretion. Posthoc analyses demonstrated a specificity of 95%-100% for unilateral disease with AV/IVC cortisol ratio >9 for one side, <2.0 for the opposite side and a CLR > 2.3. The specificity was 80%-90% for bilateral disease with AV/IVC cortisol ratio >5.1 bilaterally and a CLR < 1.1. CONCLUSIONS: Among patients with bilateral adrenal masses and ACTH-independent autonomous cortisol secretion, AVS can distinguish between unilateral and bilateral disease with high specificity and may guide surgical management.

Primary Adrenal Lymphoma as a Rare Cause of Primary Adrenal Insufficiency: Challenges in Management and a Review of the Literature.

Background/Objective: Primary adrenal lymphoma (PAL) is an aggressive form of lymphoma associated with adrenal insufficiency (AI) in most cases. It requires a histologic confirmation unlike other cases of primary AI. Case Report: We report a case of a 66-year-old man who presented with AI with symptomatic hypotension and hypo-osmolar hyponatremia. Ultrasound and computed tomography scans revealed bilateral bulky adrenal masses that were avid on fluorodeoxyglucose positron emission tomography scan. The diagnosis of PAL was confirmed with adrenal biopsy. He was treated with rituximab-based chemotherapy, which was complicated by several endocrine challenges, including worsening diabetes, multiple adrenal crises, prolonged hyponatremia, and refractory hypokalemia requiring spironolactone. He eventually developed central nervous system disease and was treated with palliative intent. Discussion: AI in the setting of PAL can constitute both diagnostic and therapeutic challenges, including significant electrolyte imbalances as discussed in this case report. Conclusion: It is important to have a high suspicion for PAL, especially in the presence of bilateral adrenal masses and AI. Early adrenal biopsy is required for diagnosis. Multidisciplinary care is vital to manage complications that arise during the disease course and treatment.

Metastasis of Melanoma to the Adrenal Glands: A Case Report and Literature Review.

Immune checkpoint inhibitors have significantly improved the prognosis of metastatic melanoma, but metastases to the adrenal glands remain highly resistant to these new treatments. Adrenal gland metastases from melanoma can present in an unusual manner, such as in this report, making it diagnostically and therapeutically challenging. In this case report, we present a patient with histologically confirmed metastatic melanoma to the adrenal glands, a large intracardiac mass suspicious for metastatic disease, and an inferior vena cava thrombus. We review the existing literature to explain the unique characteristics, clinical relevance, pathogenesis, diagnosis, and treatment of adrenal gland metastases from melanoma.

Nonseminomatous Germ-Cell Tumor Presenting as Bilateral Adrenal Masses.

OBJECTIVE: Many tumors can metastasize to the adrenal glands, making the diagnosis of adrenal masses challenging. Awareness that rare primary tumors can metastasize to the adrenals and consideration of biopsy for their diagnosis, sometimes at extra-adrenal sites, is essential to prevent unnecessary adrenalectomies and facilitate the right treatment. We report a rare case of bilateral adrenal masses due to metastasis from a nonseminomatous germ-cell tumor of a retroperitoneal lymph node origin. METHODS: The diagnosis of the adrenal masses from the nonseminomatous germ-cell tumor of a retroperitoneal lymph node origin was based on a retroperitoneal lymph node core biopsy. An initial core biopsy of the adrenal gland revealed necrotic tissue and inflammatory cells without evidence of malignancy. Due to nondiagnostic findings, the core biopsy was repeated, which showed degenerating cells with a high mitotic index and immunohistochemical staining positive for vimentin, suggesting the possibility of a high-grade sarcoma. A retroperitoneal lymph node biopsy was performed. The patient was started on chemotherapy. RESULTS: A 34-year-old man presented with acute left upper-abdominal pain of 2 weeks and tenderness on the left upper quadrant of the abdomen, and he was found to have bilateral adrenal masses. Laboratory results showed the following: adrenocorticotropic hormone 41 pg/mL (7-69 pg/mL), metanephrine <0.1 nmol/L (0-0.49 nmol/L), normetanephrine 0.99 nmol/L (0-0.89 nmol/L), and morning cortisol 3.1 µg/dL after a 1-mg dexamethasone-suppression test. His dehydroepiandrosterone sulfate level was 62 µg/dL (120-520 µg/dL), and 17OH progesterone level was 36 ng/dL (<138 ng/dL); androstenedione and serum estradiol levels were normal. Laboratory tests for tumor markers revealed the following: testosterone 21 ng/dL (241-827 ng/dL), prostate-specific antigen 0.57 ng/mL (0-4 ng/mL), alpha-fetoprotein 1.9 IU/mL (0.6-6 IU/ml), and beta-human chorionic gonadotropin 134 mIU/mL (0-1 mIU/mL). CONCLUSION: We report a rare case of rapidly progressing adrenal masses in a young man, found to have metastasized from nonseminomatous germ-cell tumors. Histopathologic confirmation of the metastatic tumor was done, which prevented unnecessary adrenalectomy. The patient received appropriate chemotherapy.

Bilateral Adrenocortical Carcinoma Presenting as Acute Adrenal Insufficiency.

The presentation of adrenocortical carcinoma (ACC) with bilateral adrenal masses and acute adrenal insufficiency is exceedingly rare and has only been seen in anecdotal case reports. Herein, we describe the case of a 50-year-old male who presented with a painful abdominal lump, loss of weight and appetite, several episodes of vomiting, and hypotension. Imaging studies were suggestive of bilateral adrenal masses and a lung mass. Hormonal work-up was suggestive of acute adrenal insufficiency, with the adrenal masses being non-secretory. An ultrasound-guided biopsy from one of the adrenal masses was suggestive of ACC, thus confirming the diagnosis as bilateral ACC with distant metastases. Bilateral adrenalectomy was planned for the patient, but unfortunately, he succumbed to his disease before the surgery.

BILATERAL ADRENAL AND TESTICULAR MASS IN A PATIENT WITH CONGENITAL ADRENAL HYPERPLASIA.

INTRODUCTION: Congenital adrenal hyperplasia (CAH) autosomal recessive disorders characterized by impaired adrenal steroid hormone synthesis. The most common form is 21-hydroxylase deficiency (21OHD). Testicular adrenal rest tumors (TARTs) are benign intratesticular masses that occur in male patients with CAH. TARTs are quite common in patients with 21OHD who were diagnosed late. CASE REPORT: A 41-year-old male patient with CAH secondary to 21OHD. The patient was referred to our endocrinology department from the andrology clinic for bilateral adrenal masses. Bilateral orchiectomy had been performed due to bilateral testicular masses and azoospermia two years ago. The pathology was reported as Leydig cell tumor. In hormonal assessment, baseline cortisol levels were low, 17-hydroxyprogesterone levels with baseline and after cosyntropin stimulation test were high. As a result of clinic and laboratory assessment, the patient was diagnosed with simple virilising CAH due to 21OHD and adrenal insufficiency. Then, prednisolone replacement was initiated. Bilateral orchiectomy tissue blocks of the patient were re-assessed and were considered TART. Magnetic resonance imaging revealed bilateral adrenal masses with 88x55 mm on the right and 41x22 mm on the left. Laparoscopic right adrenalectomy was applied and pathology was reported as myelolipoma. Follow-up of the mass on the left adrenal gland is ongoing. The patient is monitored under prednisolone and testosterone replacement therapy. Early diagnosis of CAH is very important because of the complications it causes. It should be considered especially for bilateral testicular and/or adrenal masses. Both fertility and adrenal glands can be protected with an early diagnosis and an early glucocorticoid replacement.

Computed tomography and (18)F-fluorodeoxyglucose positron emission tomography/computed tomography findings in adrenal candidiasis and histoplasmosis: two cases.

We report the contrast-enhanced computed tomography (CT) and (18)F-fluorodeoxyglucose positron emission tomography findings in adrenal histoplasmosis and candidiasis. Both demonstrated bilateral hypermetabolic heterogeneous adrenal masses with limited wash-out on delayed CT. Adrenal candidiasis has not been previously reported, nor have the CT wash-out findings in either infection. The adrenal imaging findings are indistinguishable from malignancy, which is more common; but in this setting, physicians should be alert to the differential diagnosis of fungal infections, since it can be equally deadly.

Adrenal imaging (Part 2): Medullary and secondary adrenal lesions.

Adrenal malignancies can be either primary adrenal tumors or secondary metastases, with metastases representing the most common malignant adrenal lesion. While imaging cannot always clearly differentiate between various adrenal malignancies, presence of certain imaging features, in conjunction with appropriate clinical background and hormonal profile, can suggest the appropriate diagnosis. The second part of the article on adrenal imaging describes adrenal medullary tumors, secondary adrenal lesions, bilateral adrenal lesions, adrenal incidentalomas and provides an algorithmic approach to adrenal lesions based on current imaging recommendations.

Mainly adrenal gland involving NK/T-cell nasal type lymphoma diagnosed with delay due to mimicking adrenal hemorrhage.

A 29-yr-old man, presented with abdominal pain and fever, had an initial computed tomography (CT) scan revealing low attenuation of both adrenal glands. The initial concern was for tuberculous adrenalitis or autoimmune adrenalitis combined with adrenal hemorrhage. The patient started empirical anti-tuberculous medication, but there was no improvement. Enlargement of cervical lymph nodes were developed after that and excisional biopsy of cervical lymph nodes was performed. Pathological finding of excised lymph nodes was compatible to NK/T-cell lymphoma. The patient died due to the progression of the disease even after undergoing therapeutic trials including chemotherapy. Lymphoma mainly involving adrenal gland in the early stage of the disease is rare and the vast majority of cases that have been reported were of B-cell origin. From this case it is suggested that extra-nodal NK/T-cell lymphoma should be considered as a cause of bilateral adrenal masses although it is rare.
