Paraganglioma Associated with Hypoglycemia

Abstract

A 63-year-old female had frequent attacks of palpitations with sweating and occasional loss of consciousness for 7 years before admission. These symptoms and documented hypoglycemia (blood glucose : 46mg/dl) suggested insulinoma, but computed tomography demonstrated a retroperitoneal tumor which was diagnosed as a paraganglioma by histological examination of the resected specimen.
