Pelvic MRI: Sagittal T2-weighted image, showing an intraperitoneal tumor with tissular and cystic signal. The tumor is separated from the uterus. The cystic areas appear hyperintense on T2-WI. And the tissular parts present heterogeneous signal on T2 sequence with hypointense areas corresponding to fibrotic tissue. The solid component of the tumor enhances strongly and heterogeneously after gadolinium injection.
