The following is a case report of an 80-year-old woman, who, to the authors' knowldge, is the oldest reported patient to have an extrahepatic portal vein aneurysm. As in this patient, most findings of this rare lesion are incidental. The authors made the presumptive diagnosis of a congenital etrrahepatic portal vein aneurysm based on the location, the absence of underlying lier, pancreatic, biliary duct, gall bladder disease, or any other apparent cause. Gray scale and color duplex sonography were used to make the diagnosis in this case.
