Metastatic disease to the pancreas: evaluation by computed tomography.

Seven patients with one or more pancreatic masses due to metastases to the pancreatic parenchyma were studied by CT. Two patterns were observed. Three patients had multiple nodules studding the pancreatic surface. Four patients had a solitary focal mass indistinguishable from a primary pancreatic neoplasm. In patients with a solitary focal lesion surgical biopsy may be necessary to differentiate between metastasis and primary pancreatic carcinoma.
