内分泌非活性副腎皮質腺腫の1例

Abstract

A 49-year-old female was admitted for evaluation of the abdominal mass which had been incidentally found by ultrasonography during the work up of diabetes mellitus. There was no evidence suggesting hormonal hyperactivity along with the clinical symptoms and the laboratory data. CT scan revealed a small round mass over the right renal upper pole which was in homogeneously enhanced by contrast dye. Right adrenal venography showed the round mass compressing the right adrenal central vein, and hormonal sampling in several portions of the venous system gave unremarkable results. The abdominal mass was resected and the histologic diagnosis was benign adrenal cortical adenoma. This case of nonfunctioning adrenal cortical adenoma is presented, and the management of asymptomatic adrenal tumors incidentally found was discussed.
