Abstract
Objective:To analyze and summary the application value of 16 slice spiral CT in the diagnosis of retroperitoneal stromal tumor.Methods:15 cases with retroperitoneal stromal tumor were selected from June to November 2012.They were as the research objects.The performance characteristics of 16 slice spiral CT were retrospectively analyzed.Results:In the 15 cases with retroperitoneal stromal tumor,2 cases were benign tumor,3 cases were low potential of malignant tumor,and 10 cases were malignant tumor.The CT manifestations of 15 cases had retroperitoneal soft tissue mass.The specific location:6 cases were midsection,9 cases were middle and lower abdomen.The tumor diameter range was 3.1~25cm,and the average was 8.5±1.6cm. The lump shape:4 cases were quasi-circular,5 cases were lobular,6 cases were random shape.5 cases were CT scan density uniform,10 cases were nonuniform,2 cases were half a dotted calcification,3 cases were tumor with bleeding.4 cases were CT enhanced scan even moderate strengthening,2 cases were uneven reinforced,6 cases were crisscrossed rail sample reinforcement, 3 cases were small blood vessels of edge and center.In the CT scan of 15 patients,there were visible around the mass and the organs in a centrifugal displacement,involvement of adjacent vascular,adrenal,ureter,5 cases were with ascites,2 cases were liver metastasis,3 cases were lung metastasis.Conclusion:The spiral CT performance characteristics of retroperitoneal stromal tumor is obvious.It is avail to rapid diagnosis and differential diagnosis of stromal tumor.关键词
