Intrauterine arterial pseudoaneurysm, a rare cause of per vaginal bleeding

The current study evaluated two cases of pervaginal bleeding subsequent of intrauterine arterial pseudoaneurysm. Each case was complaining of intermittent attacks of heavy vaginal bleeding: one case with history of cesarean section and the other case after uterine curettage. Intrauterine arterial pseudoaneurysm can be caused by a traumatic injury to the vessel wall with subsequent formation of periarterial hematoma that liquefies forming periarterial bloody cyst, which communicates through the narrow neck with the arterial lumen. Transvaginal ultrasound aided with color duplex capability is an accurate tool for assessment.
