A large pelviabdominal multilocular complex soft and cystic mass lesion measuring about 14.8 x 7.8 x 12.5 cm along its maximum axial and CC dimensions respectively. The soft tissue component is seen eliciting low to intermediate T1, heterogeneous predominantly high T2 signal with restricted diffusion in the DWI. It shows heterogeneous enhancement in the post-contrast series. Innumerable variable-sized cystic structures are seen eliciting low T1 and bright T2 signal. The largest of them measures about 7.3 x 5.4 cm in diameter.
The uterus is average in size and of normal myometrial signal. The endometrium is seen thickened measuring about 18 mm in thickness, yet it appears hyperintense. Preserved junctional zone. Normal MR appearance of the cervix and the vagina.
Preserved follicular activity of the right ovary showing a dominant follicle measuring about 2.75 x 2 cm in diameter. Inconspicuous left ovary.
Prominent bilateral external iliac and inguinal lymph nodes.
Moderate amount of free pelviabdominal collection.
