Abstract:
Objective To evaluate the features of solid-pseudopapiHary tumors of pancreas (SPTP),and to compare with the clinical and pathological findings in order to improve the diagnostic accura-cy.Methods The CT appearances were analyzed retrospectively in 5 patients with pathologically proven SPTP.There were 4 women and 1 man,with the mean age of(16.20±7.49)years.Plain CT and contrasted CT were performed in all 5 cases.Results The tumors of 4 caseswerelocatedinthe head and neck of pan-creats and 1 case was in the body and tail of pancreas.Clear tumor margins were seen in all cases.The mean diameter of these tumors was 5.2 cm(3.0-9.0 cm).Two cases were predominantly composed of cystic por-tions,2 cases were mainly composed of solid portions,and 1 case was composed of similar proportions of solid and cystic portions.Inhomogeneous enhancement Was rewealed in contrasted CT scan,but Was lower in both phase than normal pancreas.Tumor border discontinuous ring-shape calcification was seen in 1 case,dilata-tion of the main pancreatic duct Was demonstrated in 1 case and no metastasis were seen.Conclusions Certain CT features may suggest the diagnosis of SPTP.CT combined with the clinical feature is helpful to the diagnosis.
