Figure 4.

Coexistence of fibroids and dermoid cyst in a 33-year-old woman, presenting for pre-embolization evaluation. Sagittal T2-weighted image reveals a large fibroid (F). A complex, heterogeneous mass (D) is seen in the pouch of Douglas with mixed high T2 signal intensity. On further sequences it was demonstrated to arise from the right ovary. Additional T1-weighted fat-saturated contrast-enhanced image (not shown), demonstrated the presence of macroscopic fat, allowing the pre-embolization diagnosis of a mature dermoid cyst. Benign adnexal masses are not a contraindication for UAE.
