Uterine arteriovenous vascular malformation masked by partial molar pregnancy: diagnostic challenge and subsequent embolic treatment.

Uterine arteriovenous vascular malformations (UAVM) are uncommon and usually present in women of reproductive age. When these occur in a pregnant patient or in the immediate postpartum period, clinical presentation may overlap with several other entities such as retained products of conception (RPOC), postpartum endometritis, as well as gestational trophoblastic disease (GTD) [1]. We present a case of a UAVM that presented with life-threatening vaginal bleeding several months after dilatation and curettage (D&C) of a molar pregnancy. The UAVM was diagnosed with ultrasound (US) and magnetic resonance imaging (MRI), and subsequently treated with transarterial embolization (TAE).
