Cervicomedullary junction arteriovenous malformation(AVM) is extremely rare. The authors present a case of a cervicomedullary junction AVM in a 31-year-old woman presenting with recurrent intraventricular hemorrhage(IVH). Magnetic resonance imaging revealed the AVM(of a size of approximately 2X2.5X4cm) extending from a lower medulla to C2-3 level. Vertebral angiography demonstrated a tightly coiled vascular mass with multiple feeders (radiculomedullary arteries) and irregular-shaped aneurysm at distal part of feeder originating at right C-1 level. The patient underwent superselective embolization of upper nidus and the aneurysm. The pertinent literature is reviewed, and diagnostic and therapeutic implications are discussed.
Key Words: Cervicomedullary junction; Arteriovenous malformation; Intraventricular hemorrhage; Angiography; Embolization
