The whole left ovary is hugely enlarged, measures approximately 8.6 x 7.6 x 10.4 cm. There is a large heterogeneous soft tissue mass lesion, as the following: The major component is fat intensity (which appears bright in T1, T2 and suppressed in STIR and T1 FAT SAT). There is a target-like (doughnut sign) lesion measuring 5.7 x 6.8 x 5.7 cm, it shows hypointense on T1 (containing dots of hyper signal intensity), intermediate signal on T2 and hyperintense STIR sequences. It shows restriction diffusion on DWI, which may suggest Rokitansky nodules. There is no significant enhancement after IV contrast administration. Features are representing ovarian dermoid cyst/ mature cystic teratoma.
