| PURPOSE : The purpose of this study was to evaluate the usefulness of endoscopic ultrasonography (EUS) in the differential
diagnosis of benign and malignant intraductal papillary mucinous tumor of the pancreas.
MATERIALS and METHODS : Seven patients with intraductal papillary mucinous tumor of the pancreas confirmed by
operation underwent EUS. After evaluation of findings of EUS, these observations were compared with pathologic
findings, and then reevaluated them according to the histologic grade of malignancy.
RESULTS : According to the pathologic specimens, three cases of them were malignant and the remaining 4 cases
were benign. The subtypes of them were as follows: 2 main duct type, 2 branch duct type, and 3 combined type.
All malignant tumors showed the main pancreatic duct dilatation (5-15 mm, mean 9.7mm), whereas all benign
tumors showed no dilatation of the main pancreatic duct on EUS. The mural nodules of the malignant tumors
(12-14mm) were significantly larger than those of benign lesions (3-4mm), significantly.
CONCLUSION : EUS is useful for diagnosing intraductal papillary mucinous tumor of the pancreas, particularly for
predicting malignancy. |
