Ovarian mature cystic teratoma


The T1 and T2 hyperintense components nilling on fat suppression sequence are consistent with fat content. The T1 iso- and T2 hyperintense signals that are persistent on fat suppression sequences represent high proteinaceous material.

A Rokitansky nodule is seen as a round structure protruding into the cyst lumen which is characteristic for mature cystic teratoma of the ovary. It can reach a large size, as in this case.
