Preoperative pelvic magnetic resonance imaging. Preoperative images show a tumor (yellow arrow) that was a cystic mass measuring 90 × 65 mm with a smooth margin and homogeneous signal intensity on the right dorsal side of the uterus (a–d). Coronal image (c), sagittal image (d). T1-weighted images present slightly higher signals than those of water, and T2-weighted images show low signals. No apparent communication was found between the cyst and the intestinal tract
