Uterine arteriovenous malformations are uncommon but pose the risk of potentially life-threatening hemorrhage. A 29-year-old pregnant female presented with vaginal spotting, after which ultrasound diagnosis of missed miscarriage was made and medical management undertaken. Vaginal spotting continued post-treatment which led to repeat pelvic ultrasound and subsequent magnetic resonance imaging which confirmed a uterine arteriovenous malformation masquerading as retained products of conception. Uterine instrumentation with dilatation and curettage could have been potentially devastating. The patient was successfully treated with uterine artery embolization.
