Persistent cornual pregnancy mimicking uterine arteriovenous malformation: a case report

BACKGROUND: Uterine arteriovenous malformation(AVM) refers to the abnormal direct traffic between uterine arteries and veins, which can be characterized by the imaging examination, showing increased uterine vascularity and arteriovenous shunting. However, similar imaging manifestations can also be seen in a variety of conditions including retained production of conception, gestational trophoblastic disease, placental polyp, and vascular neoplasm. CASE PRESENTATION: Here we present a case of a 42-year-old woman who was suspected of suffering uterine AVM indicated by Doppler sonography and magnetic resonance imaging but was finally diagnosed with a persistent ectopic pregnancy located on the right uterine corner by pathology after laparoscopy. She recovered well after surgery. CONCLUSION: Uterine AVM is a rare and serious condition. In general, it presents special radiological manifestations. However, when complicated with other diseases it can also be distorting. Standardized diagnosis and management are important.
