Palliative Interventional Embolization for Finding of Ectopic Noradrenaline-Secreting Pheochromocytoma in the Nasal Cavity

摘要

A 52-year-old male who had chronic hypertension for several years presented with abrupt epistaxis. The CT scan revealed a 40 mm x 40 mm mass in the nasal cavity intended to the maxillary sinus and the base of skull. Nasal endoscope biopsy and serum/urinary catecholamine detection conformed an ectopic noradrenaline-secreting pheochromocytoma. The present research was to discuss the clinical characteristics of the rare pheochromocytoma and the palliative interventional embolization for it.
