Abstract

Mature ovarian teratoma (dermoid cyst), a germ cell neoplasm, is one of the most common ovarian tumors. It is composed of derivatives of three germ cell layers. A mature ovarian teratoma with intracystic fat globules is rare. The pathogenesis on the formation of fat globules is unclear. Here we present a pathologically proven cystic ovarian teratoma with three large floating fat globules in a young woman with CT and MR findings.

Keywords: Ovary, Neoplasm, Teratoma
