[Abstract] Objective: To investigate chronic pancreatitis whose MR cholangiopancreatography (MRCP) showed four-segment-sign.Materials and Methods: Retrospective analysis of pathologically confirmed clinic and imaging data of four chronic pancreatitis cases, all of which had been undergone CT enhanced scanning and MRCP examination before surgery, and one case with further MRI enhanced scanning.Results: Three out of four cases have mass in the pancreatic head, one case no significant mass, two cases showed slightly low density mass at each CT enhancement stage compared with normal parenchyma, one case equal density mass, one case no abnormal contrast enhancement, one case showed slightly lower signal mass at each MRI enhancement stage compared with the normal parenchyma with duct-penetrating sign at portal venous phase. All four cases showed the four-segment-sign in MRCP.Conclusions: MRCP of chronic pancreatitis can be expressed as four-segment-sign, more common occurrence in mass-type focal pancreatitis. Four-segment-sign is not specific signs of pancreatic cancer, and further diagnosis is depends on enhanced CT or MRI scanning.
