Spontaneous regression of enhanced myometrial vascularity


Enhanced myometrial vascularity (EMV) is frequently misdiagnosed as a uterine arteriovenous malformation (AVM) and often thus treated with uterine artery embolization, which may lead to ovarian insufficiency. Thus, conservative management with watchful waiting should be considered instead, particularly in women in the childbearing period.

This patient presented with lower abdominal pain one month after miscarriage with no surgical interference, consistent with a history of EMV which is typically seen as a complication of pregnancy. 7 weeks later the EMV disappeared spontaneously. A true AVM will not spontaneously regress.
