Patient Data

Gender: Female
CT

A lobulated well encapsulated lesion is seen in pelvis, in the midline, however appearing to arise from left adnexal (ovarian) region. Thin isodense area is seen in the periphery of the lesion, likely to represent ovarian stroma. Lesion is predominantly of fat-attenuation, with soft tissue attenuation solid areas within. No obvious calcification or post-contrast enhancement is seen.

Differential diagnosis:

  1. Ovarian lipoma
  2. Ovarian lipoleiomyoma1
  3. Colonic lipoma (case reference)

Final diagnosis:

Ovarian dermoid
