Mature teratoma in a 33-year-old woman. (a) Axial T1-weighted, (b) axial fat-suppressed T1-weighted, (c) sagittal T2-weighted and (d) axial fat-suppressed T2-weighted images show a well-defined ovalar mass with fat tissue (*) with high signal intensity both on T1-weighted and T2-weighted images and signal loss on fat-suppressed sequences. A hypointense nodule (white arrowheads) is seen within the lesion, as well as a solid component (white arrows). (e) Photomicrograph (H&E X20) shows cystic space lined by mature epidermis. Skin appendages and neural tissue are seen in the wall
