adrenal tumour

An adrenal tumor is a growth on the adrenal gland, which sits atop each kidney. These glands have two parts: the inner medulla, producing epinephrine and norepinephrine, and the outer cortex, producing steroid hormones like cortisol and aldosterone.

A specific type of adrenal medulla tumor, a pheochromocytoma, can cause episodes of high blood pressure, palpitations, and sweating due to excessive hormone secretion. Tumors in the adrenal cortex can lead to conditions like Cushing syndrome (excess cortisol) or primary aldosteronism (excess aldosterone), characterized by high blood pressure and electrolyte imbalances. Treatment often involves surgical removal of the tumor.
