Presentation
Pelvic pain and palpable mass on physical exam.
Patient Data
A 95×65×70 mm thick walled cystic lesion with areas of fat density and calcification is present at the pelvis, which seems to originate from the left adnexa and is most consistent with dermoid cyst.
In addition, a small amount of free fluid is present in the pelvis.
Case Discussion
CT has high sensitivity in the diagnosis of the ovarian dermoid cyst and typically demonstrates fat, fat-fluid level, calcification (sometimes dentiform), Rokitansky protuberance, and tufts of hair. The presence of most of the above tissues is diagnostic of ovarian cystic teratomas in 98% of cases.
