pheochromocytom

Pheochromocytoma is a rare tumor that produces excess catecholamines, affecting heart rate, blood pressure, and metabolism. This guide explores essential topics, including the role of epinephrine and norepinephrine, symptoms such as hypertension and cardiac arrhythmias, as well as diagnostic tests like CT, MR, and I131-MIBG. Treatment strategies are highlighted, with an emphasis on alpha and beta blockers, cold stimulation tests, and options for management. It discusses the long-term outlook, with over 75% achieving normal health within a month, and emphasizes the importance of monitoring during and after treatment.
