Bladder endometriosis

To diagnose bladder endometriosis at MRl, natural bladder distention by urine helps to identify small T2- and Tl-hypointense nodules, most often located in the bladder dome, anterior to the vesicouterine pouch. Small Tl-hyperintense portions may co-ex-ist and correspond to haemorrhagic portions of the lesion. At contrast-enhanced imaging, the lesion enhances more than the noninvaded normal bladder detrusor [35] (Fig. 11.2).
