Pancreatic arteriovenous malformation presenting as cysts: Doppler sonographic diagnosis.

A 50-year-old man presented with multiple lesions resembling cysts throughout the pancreas on gray-scale sonography. Pulsatile blood flow detected within the lesions on color Doppler sonography led to the diagnosis of pancreatic arteriovenous malformation (PAVM). Most previously reported PAVMs have been described as having a poorly defined, reticular, or mosaic-like hypoechoic appearance on gray-scale sonography; the cystic appearance of the PAVM seen in our case is unusual.
