We present a non-icteric case, in which an ampullary polypoid lesion was clearly demonstrated by ultrasonography, suggesting carcinoma of the ampulla of Vater. The lesion was a 3 cm in diameter, spherical tumor with a polypoid surface, and internal hyperechogenicity. The patient underwent a curative pylorus-preserving pancreaticoduodenectomy.
