The MRI sequences demonstrate:
- enlarged uterus with diffuse thickening of the junctional zone endometrium-myometrium (18-25 mm) of intermediate signal on T1, homogeneous low signal intensity on T2 with foci of high signal within, indicating menstrual haemorrhage into the ectopic endometrial tissues
- numerous small intramural and subserosal leiomyomas are noted
- bilateral well-defined ovarian masses of intermediate signal on T1, low signal on T2 with a punctate central area of high signal (mainly on the left) and moderate enhancement on postcontrast sequences.
- irregular circumferential thickening with enhancement of the sigmoid colon, and restricted diffusion on DWI/ADC. Infiltration of the mesocolon with thickening and enhancement of the adjacent peritoneal reflections
