[Bilateral adrenal pheochromocytoma. A case report]

Abstract

The authors report a case of apparently isolated bilateral adrenal phaeochromocytoma in a 25-year-old man presenting with abdominal pain and neurosensory signs of HT, but ignored and complicated by heart failure. Ultrasonography and abdominal CT revealed a bilateral adrenal tumour. The hormonal assessment, particularly metanephrines and normetanephrines, was normal. The diagnosis of phaeochromocytoma was proposed despite the negative hormonal assessment and was supported by positive MIBG scintigraphy, compatible with bilateral adrenal phaeochromocytoma with no other sites. Treatment consisted of right adrenalectomy and left tumour excision. The postoperative course was uneventful, and 3-year follow-up showed regression of the functional symptoms and control of blood pressure without any other treatment.
