Abstract:
A 42-year-old male presented with polyuria, polydipsia and weight loss. His initial physical exam showed a paucity of cushingoid features. Diagnostic work up was consistent with an ectopic adrenocorticotropic hormone (ACTH) secretion. Imaging studies showed a small anterior mediastinal lesion without additional metabolically active tumors. Fine needle aspiration was consistent with a thymic neuroendocrine tumor. Following radical thymectomy, plasma ACTH and cortisol levels remained elevated. Despite medical management, he died within 2 months of presentation of disseminated intracranial aspergillosis. This case underscores the diagnostic dilemma of occult ectopic ACTH-secreting tumors and the fatal consequence of opportunistic infections.

Adrenal Gland Disorders
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss. Congenital adrenal hyperplasia, a genetic ailment causing...
Hormones of the Adrenal Glands
The adrenal cortex, a powerhouse of hormone synthesis, generates over two dozen corticosteroid hormones. The zona glomerulosa produces mineralocorticoids, exemplified by aldosterone, influencing the electrolyte composition of body fluids. The synthesis of glucocorticoids such as cortisol and...
Anatomy of the Adrenal Glands
These glands possess a distinctive yellow tinge due to the stored cholesterol and fatty acids required for hormone synthesis. They are encased in a fibrous capsule and cushioned by fat.
