A Case of Pheochromocytoma Manifested by Generalized Seizure / 대한내분비학회지

ABSTRACT

Pheochromocytoma is originated from chromaffin cells of sympathetic nervous system and clinical symptoms are caused by catecholamine released from tumor. In typical cases, periodic attacks of hypertension, palpitation, headache, and sweating are main symptoms. But, the diagnosis of pheochromocytoma is sometimes difficult since its clinical presentation is quite variable. We evaluated a 25-year-old woman who was admitted because of left flank pain and seizure. She had a history of hemoptysis and toxemia. During the hospitalization, she experienced generalized seizure once more. The clinical diagnosis of pheochromocytoma was proven by highly elevated urinary catecholamines and confirmed histologically after operation. We think it is the first case report of pheochromocytoma manifested by seizure in korea, so we report this case with literature review.
