Pseudocysts of the adrenal gland

Abstract

Three cases of pseudocysts or hemorrhagic cysts of the adrenal gland were encountered in female patients who presented with loin pain. The adrenalectomy specimens contained cystic structures; 2 had fibrous walls containing organizing blood clot, the remaining lesion was thin walled and contained blood stained fluid. Fat, normal adrenal cortical tissue and calcification were found within the cysts. These lesions (arising from vascular anomalies) require separation from hemorrhagic adrenal neoplasms. Awareness of adrenal pseudocysts and careful attention to the histological features aids this distinction.
