Ovarian dysgerminoma is a rare germ cell tumor accounting for 1%-2% of all malignant ovarian tumors and is generally associated with a good prognosis. The condition is more frequent in young women and can arise in dysgenetic gonads that contain gonadoblastomas. Imaging findings, particularly MRI, have a prominent role in the early and correct identification of ovarian dysgerminoma, the most common ovarian malignant germ cell tumor. On CT and MR images, ovarian dysgerminoma often appears as a large, solid mass. The edematous condition of characteristic fibrovascular septa can be well displayed by imaging, which can guide the radiologists to make an accurate diagnosis. This article describes 2 cases of patients with ovarian dysgerminoma who presented with pelvic pain. Imaging showed a right ovarian mass that was surgically and histologically confirmed.
