Primary adrenal insufficiency is a rare disease and can masquerade as other conditions; therefore, it is sometimes incorrectly diagnosed. Herein, we reported the case of a 39-year-old Vietnamese male with primary adrenal insufficiency due to bilateral adrenal tuberculosis. The patient presented to the emergency room with acute adrenal crisis and a 3-day history of nausea, vomiting, epigastric pain, and diarrhoea with a background of 6 months of fatigue, weight loss, and anorexia. Abdominal CT revealed bilateral adrenal masses. Biochemically, unequivocal low morning plasma cortisol (<83 nmol/L) and high plasma adrenocorticotropic hormone levels were consistent with primary adrenal insufficiency. There was no evidence of malignancy or lymphoma. As the patient was from a tuberculosis-endemic area, extra-adrenal tuberculosis was excluded during the work up. A retroperitoneal laparoscopic left adrenalectomy was performed, and tuberculous adrenalitis was confirmed by the histopathological results. The patient was started on antituberculous therapy, in addition to glucocorticoid replacement. In conclusion, even without evidence of extra-adrenal tuberculosis, a diagnosis of bilateral adrenal tuberculosis is required. A histopathological examination has a significant role along with clinical judgement and hormonal workup in establishing a definitive diagnosis of adrenal tuberculosis without evidence of active extra-adrenal involvement.
Primary adrenal insufficiency can be misdiagnosed as other mimicking diseases, such as gastrointestinal illness, leading to diagnostic pitfalls.
Adrenal insufficiency can be confirmed with significantly low morning plasma cortisol levels of <83 nmol/L without a dynamic short cosyntropin stimulation test.
Tuberculous adrenalitis is an uncommon treatable condition; however, it remains an important cause of primary adrenal insufficiency, especially in developing countries. In the absence of extra-adrenal involvement, adrenal biopsy plays a key role in the diagnostic process. Alternatively, adrenalectomy for histopathological purposes should be considered if CT scan-guided fine needle aspiration is infeasible in cases of small adrenal masses.
Primary hepatic neuroendocrine tumor (PHNET) is a rare type of neuroendocrine tumor (NET) that is also a primary hepatic tumor. Patients are present with almost no specific clinical symptoms and typically present with negative test results and atypical imaging characteristics; therefore, the differentiation of PHNET from other types of primary hepatic masses can be very difficult. In this article, we describe a case of PHNET that mimicked a liver helminth infection in a 57-year-old man. The diagnosis of PHNET in this patient was challenging, and the final diagnosis was based on imaging, histopathology features, and long-term follow-up.
An uncommon type of neuroendocrine tumor (NET) is a primary hepatic neuroendocrine tumor (PHNET).
Primary hepatic neuroendocrine tumors are rare NET lesions found in the liver, characterized by non-specific clinical and imaging results, which can be easily confused with other liver lesions, including HCC and parasitic lesions.
To have a conclusive diagnosis and classification, a mixture of many medical assessment techniques, such as imaging, gastrointestinal endoscopy, nuclear medicine, anatomy, including histopathology, and immunohistochemistry, is essential.
