A, Axial contrast-enhanced CT image before treatment shows large, solid mass (arrows) in pancreatic tail and multiple hypervascular liver metastatic lesions (arrowheads). Internal linear calcification is present in pancreatic mass.
B, Axial contrast-enhanced CT image obtained 3 months after treatment shows marked decrease in size of pancreatic mass (arrows) and liver metastatic lesions (arrowheads) without change in solid enhancing nature of tumors, likely representing partial response to cytotoxic chemotherapy.
