Incidental Pelvic Arteriovenous Malformation

A 39-year-old man underwent computed tomography (CT) for abdominal pain and nausea. A 5-cm right internal iliac vascular aneurysm and likely arteriovenous malformation (AVM) was incidentally noted by CT, which was also positive for a 2-cm stone in the gallbladder neck. He underwent uneventful cholecystectomy and was then referred to interventional radiology for consultation regarding the internal iliac aneurysm. The patient was asymptomatic from the AVM (Schobinger stage 1). Given the large aneurysm and  the propensity for most AVMs to progress throughout a lifetime,1 planning angiography was performed to assess the AVM and anatomic considerations for treatment.
