Abstract:
Objective To investigate the application of multi-slice spiral computed tomography(MSCT) in the diagnosis of solid pseudopapollary tumor of the pancreas (SPTP). Methods Clinical data and CT films of 12 patients with SPTP were retrospectively analyzed from January 2003 to December 2008. Results SPTP presented a typical cystic lesion with well-limited silhouette and no intensification in the cyst on enhanced CT scan. However, a slight to moderate enhancement in the solid components and a markedly enhanced envelope could be seen. Three dimensional images of MSCT can reveal clearly an anatomic relationship of the lesions with surrounding organs and blood vessels. Of 12 cases, there was one case showed that the envelope was incomplete, 3 with duodenal invasion, 2 with superior mesenteric vein involvement, and 1 with closed adhesion with spleen. All 12 patients underwent surgery and had only one tumor, tumor diameter ranged from 4 cm to 18 cm. The location of tumor in pancreas, the relation with surrounding tissue and the pathological presentation were helpful to make peroperative diagnosis. Three dimensional imaging technology of MSCT can offer important referrence for the preroperative evaluation and increase the diagnosis accuracy.
