ObjectiveTo investigate the imaging findings of carcinoma of body and tail of the pancreas. MethodsTotally twentythree patients with carcinoma of body and tail of the pancreas were studied. The diagnosis was proven by surgery and pathological findings. The imaging features of twentythree cases were reviewed including the location, size, shape, texture, and enhancement patterns of the tumor masses. Five cases underwent enhanced MRI examination, 18 cases underwent enhanced spiral CT examination. ResultsThe tumors located in the pancreatic body in 5 cases, located in the tail in 7 cases, and located in the body and tail of pancreas in 11 cases. The tumor masses were irregular in shape and heterogeneously hypointense from CT scan. From MR, the masses were slightly hypointense on T1WI, and slightly or mixed hyperintense on T2WI. Nineteen cases showed heterogeneous slight enhancement and four cases had no enhancement. The tumors were well demarcated in five cases, while those were poorly defined in the other 18 cases. Metastatic lymphadenopathy was shown in 16 cases, vascular invasion in 8 cases, and metastatic lesions of other organs in 3 cases. ConclusionThe carcinoma of body and tail of the pancreas shows certain characteristic imaging. CT and MRI examination can reflect the morphologic features, the hemodynamic alterations, and the involvement of adjacent structures and organs.
