Abstract

The computed tomographic and histologic appearances in 34 cases of autopsy-confirmed metastatic tumors of the pancreas including secondary malignant lymphoma are discussed. In 18 (53.8%) the pancreas appeared abnormal on computed tomography, the lesions being classified into three types: In 8 cases there was diffuse enlargement of the pancreas; in 9 cases a localized mass; and one patient had multiple low attenuated nodules within the organ. Histologic investigation revealed that metastatic carcinoma involved the pancreatic lobules. The degree of infiltration in the interlobular connective tissue was related to the invasiveness of the tumors. In the majority of cases with diffuse infiltration the pancreatic lobules were destroyed and varying degrees of proliferation of malignant cells into the interlobular septa were documented. In patients with localized infiltration there was extensive invasion of the carcinoma within the pancreatic lobule. Dilatation of the pancreatic duct and/or organ-related symptoms were occasionally seen in these cases.
