title: A large adrenal pseudocyst mimicking malignant intraabdominal tumor: a case report.
abstract: An abdominal mass was found in an apparently healthy 66-year-old man during he was undergoing a routine physical check-up. Intravenous pyelography showed a huge suprarenal cyst displacing the left kidney. Both kidneys had normal renal function. The tumor was removed transperitoneally. It contained 1600 ml hemorrhagic fluid and had small golden nodules on the inner cystic surface. Microscopically, adrenal cortical tissue was present in groups or scattered along the cystic wall, which was compatible with the diagnosis of pseudocyst. No lining epithelium was present. The differential diagnosis, pathogenesis, management, and the general features of adrenal pseudocysts were discussed.
