Initial magnetic resonance images (MRI) of the pelvis. (A) T2-weighted sagittal MRI demonstrates swelling of the posterior uterine wall and ill-defined signal intensity higher than that of myometrium (arrow). (B) T1-weighted sagittal MRI demonstrates uniform low signal intensity of the uterine corpus (arrows). (C) Diffusion weighted imaging (DWI) demonstrates high signal intensity in the posterior uterine wall (arrow). (D) Apparent diffusion coefficient (ADC) map demonstrates low signal intensity in the posterior uterine wall (arrow).
