We report a case of ependymoma of the broad ligament occurring in a 21-year-old woman. CT and MRI findings showed a 40-mm-diameter, well-demarcated cystic mass with a lobulated solid component in the right pelvis. The solid component showed heterogeneous intermediate signal intensity on T2-weighted image and prolonged mild contrast enhancement. The tumor was resected and confirmed as ependymoma based on the histologic findings along with its immunohistochemical profile. To our knowledge, this is the first report of an adnexal ependymoma describing the precise radiological characteristics that resembled those of borderline or malignant epithelial ovarian tumors.
