Magnetic resonance imaging of adrenal angiomyolipoma.
Angiomyolipoma is a benign mesenchymal neoplasm that typically occurs in the kidney sporadically or in patients with tuberous sclerosis complex. Extrarenal angiomyolipomas are uncommon, and the liver is the most common extrarenal site. Other sites reported include the bone, colon, heart, lung, parotid gland, skin, spermatic cord, gynecologic regions, and retroperitoneum. A case of an angiomyolipoma involving the right adrenal gland in a 49-year-old female patient with tuberous sclerosis is reported. The magnetic resonance (MR) imaging features are also discussed. Only 2 cases describing adrenal angiomyolipoma were found in the English literature. Neither of these 2 cases was documented in the radiology literature or discussed the MR features of adrenal angiomyolipoma.
