Pheochromocytoma | Symptoms and Treatment

The video tutorial covers pheochromocytoma, a condition caused by catecholamine-secreting tumors in the adrenal medulla. It explains the pathophysiology, including the role of chromaffin cells and the effects of catecholamines on adrenergic receptors. The classic triad of symptoms—headache, palpitations, and diaphoresis—is discussed, along with less common symptoms and potential triggers. Diagnostic methods, including urine and plasma tests, are outlined, as well as genetic testing for associated syndromes. Treatment involves surgical resection, preceded by alpha and beta adrenergic blockade.
