CT scout reveals a large blank area at the right iliac fossa that contains calcification and displaces the adjacent bowel. CT reveals a large right adnexal multiloculated cystic lesion that contains fat, fluid, and calcification. It displaces the adjacent bowel loops and compresses the right ureter causing hydronephrosis and delayed right renal excretion.
Case Discussion
Mature cystic teratoma (ovarian dermoid cyst) is a benign tumor that contains cells from all germ layers (endoderm, mesoderm and ectoderm). Diagnosis can be made by ultrasonography, CT or MRI with the detection of fat and calcification within the lesion.
