Mature cystic teratoma involving adrenal gland

Abstract

A mature cystic teratoma presented as an adrenal mass in a 57-yr-old woman. The tumor was found to be predominantly paraadrenal but focally interrupted the adrenal cortex so that an intraadrenal origin could not be ruled out. Similar lesions have been reported extremely rarely and should be considered in the differential diagnosis of hormonally silent adrenal tumors. The findings of rimlike calcification and fatty density on computed tomography may be helpful diagnostically.
