Pancreatic Arteriovenous Malformation as an Unusual Cause of Chronic Gastrointestinal Bleeding in a Patient with Early Gastric Cancer: Multimodality Imaging Spectrum with Pathologic Correlation

Arteriovenous malformation (AVM) of the pancreas is extremely rare, although it may be increasingly diagnosed due to the widespread use of cross-sectional imaging of the abdomen. Early diagnosis of this disease is important to prevent delay of treatment and resulting fatal complications. We report a rare case of pancreatic AVM in a 48-year-old man who presented with severe chronic anemia and early gastric cancer, which made diagnosis challenging. Imaging findings, including ultrasound, computed tomography, and magnetic resonance imaging, are shown, as well as the pathologic features.
