Ovarian Dysgerminomas: Role Of Imaging In Correct Diagnosis

Abstract

Ovarian dysgerminomas (OD) are rare ovarian germ cell tumors that usually affects young patients usually in 2nd and 3rd decades of life. Lower quadrant pain, adnexal mass and abdominal distension are common presentation of these tumours. Laboratory values such as beta human chorionic gonadotropin (beta-hCG) and lactate dehydrogenase may be elevated (LDH). Imaging such as ultrasound, CT and MRI can predict OD owing to its solid nature, internal calcifications and vascularized nature.  Radiologically large solid lobulated adnexal mass with elevated LDH levels  in young females strongly suggest an ovarian dysgerminoma as a probable diagnosis. OD  will respond well to fertility sparing surgery and will be monitored by imaging and LDH levels. We report two cases of ovarian dysgerminoma and role of imaging in correct diagnosis of these uncommon tumors.
