Abstract:
A 66-year-old man with symptomatic hypertensive episodes was found to have a 9-mm adrenal mass and elevated metanephrine levels. He was scheduled for an adrenalectomy for suspected pheochromocytoma. Subsequent workup revealed a large bladder mass which was found to be a paraganglioma. There is no consensus on what should be considered the standard management of primary bladder paraganglioma, including surgical technique, assessment of malignancy, and appropriate follow-up, owing to the rarity of the diagnosis.

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.
The adrenal gland comprises two distinct...
