Decidualized Endometriosis: Case Study of a Rare Condition in a Rare Location

Decidualized endometriosis is a benign condition associated with ectopic endometrial tissue that has undergone a decidual reaction during pregnancy. A case is presented of a 31-year-old female who presented to an imaging center for a follow-up sonogram after experiencing one episode of vaginal bleeding during pregnancy. A solid, highly vascular mass, with irregular borders, was seen that was not present in the sonogram two weeks prior. The mass was later revealed to be decidualized endometriosis. This is a rare condition that lacks extensive reporting in the literature. The case demonstrates a particularly odd location for this disease, in between the uterus and bladder. With multiple sonograms, it was difficult to ascertain the host of the mass. Due to the extent of vascularity within this structure, malignancy had to be considered, which led to a referral for additional testing.
