Presentation
Pelvic pain.
Patient Data
Right adnexal multiseptated cystic lesion averaging around 5.5 x 7 x 7.5 cm in maximum AP, CC and side to side dimensions. It shows mixed signal intensity of both fat and high proteinaceous material. Its wall and internal septae are mostly < 3 mm with few borderline septae of 3 and 3.5 mm.
Normal MRI features of the left ovary, no left adnexal lesions.
Minimal Douglas pouch collection.
Case Discussion
The right adnexal cystic lesion showed T1 and T2 hyperintense nulling on fat suppression sequence consistent with fat content and T1 hyper and T2 hypointense persistent on fat suppression suggestive of high proteinaceous material. Features are consistent with right ovarian mature cystic teratoma.
