Deep infiltrative endometriosis (DIE) in rectouterine pouch. Axial T1W (A), T1W fat suppressed (B), and T2W axial image (C) depict obliteration of rectouterine pouch with ill-defined stellate shaped lesion (white arrows) appearing hypointense on both T1W and T2W images with associated retroversion of the uterus. There is also presence of multiple foci seen within the lesion, appearing hyperintense on T1W and hypointense on T2W images, suggestive of haemorrhagic foci within the ectopic glands
