INTRADUCTAL MUCIN-PRODUCING TUMOR OF THE PANCREAS - DIAGNOSIS BY MR CHOLANGIOPANCREATOGRAPHY

Purpose: Our goal was to evaluate the usefulness of MR cholangiopancre atography (MRCP) for intraductal mucin-producing tumor of the pancreas (MPT). Method: Eleven patients with intraductal MPTs (six main duct t ype; five branch duct type) underwent MRCP. The findings of MRCP were compared with those of endoscopic retrograde cholangiopancreatography (ERCP). Results: In all of the cases, MRCP could disclose all dilated pancreatic ducts and cysts, some of which were not demonstrated by ERC P. MRCP did not show a signal void of mucin in any of the cases. In th e two cases of the main duct type, ERCP showed filling defects of excr escent nodules, which were not seen by MRCP. In the two cases of the m ain duct type, nodules were seen more clearly by ERCP than by MRCP. Co nclusion: MRCP and ERCP are complementary imaging modalities for intra ductal MPT.
