[Myelolipoma of the adrenals--a chance sonographic finding].

A markedly echogenic and sharply marginated suprarenal mass was found incidentally during an abdominal sonography in the case of three patients. One female patient died due to a mesenterial infarct, in the other cases the tumors were removed surgically. In two cases the histological diagnosis indicated a myelolipoma of the adrenal gland, in one case an angiolipoma attached directly to the adrenal. Myelolipoma is a benign and hormone-inactive tumorous lesion, which most commonly occurs in the adrenal gland. Knowledge of the clinical and sonomorphologic characteristics along with computed tomography helps to distinguish other tumors of the retroperitoneum. Thus, unnecessary surgical intervention can be avoided.
