Abstract

Adrenal tuberculosis remains a leading cause of primary adrenal insufficiency in tuberculosis-endemic regions. Its clinical presentation is often insidious and non-specific, leading to significant diagnostic delays. Gastrointestinal symptoms, though common in adrenal insufficiency, may dominate the clinical picture and direct attention away from the underlying endocrine disorder.
A 40-year-old Ethiopian woman presented with a five-month history of intermittent abdominal pain and recurrent non-bloody vomiting. Associated symptoms included myalgia, arthralgia, intermittent low-grade fever, night sweats, and significant unintentional weight loss. She had multiple outpatient and emergency department visits and was repeatedly treated with proton pump inhibitors and different medications for an unspecified rheumatologic condition, with no definitive diagnosis established. On admission, she was hypotensive with laboratory evaluation revealing hyponatremia and severe hyperkalemia. Morning serum cortisol was markedly reduced along with elevated ACTH, supporting the diagnosis of adrenal insufficiency. HIV serology was negative. Pre and post contrast computed tomography demonstrated bilateral enlarged heterogeneously hypo-attenuating adrenal glands with internal punctate calcifications and thin peripheral rim-like enhancement. The patient was initiated on anti-tuberculous therapy with glucocorticoid and mineralocorticoid replacement. At one-month follow-up, the patient reported marked clinical improvement with complete resolution of vomiting, improved appetite, decreased fatigue, and ability to resume usual daily activities.
This case highlights the importance of considering adrenal tuberculosis in patients from endemic regions presenting with unexplained chronic gastrointestinal symptoms, constitutional features, and electrolyte abnormalities. A high index of suspicion is essential for timely diagnosis and treatment.
