A 49-year-old woman presented at our hospital for an examination of a left adrenal tumor,incidentally found by screening abdominal ultrasound sonography. CT scan showed a left adrenal tumor,which measured 6.5×5.0cm. Twelve days later,she was admitted to our hospital with sudden severe pain in the left abdomen. CT scan showed a retroperitoneal hemorrhage caused by spontaneous rupture of the adrenal tumor. We performed left adrenalectomy. The removed tumor weighted 235g,and histological diagnosis was a benign non-functioning adrenal cortical adenoma.（Rinsho Hinyokika 58：331-333,2004）
