Abstract:
Objective To investigate the diagnostic values of CT and MRI by analysing the CT and MRI features of presacral tumor.Methods The CT and MRI imaging features of 37 cases of primary presacral tumor with surgical pathology were analyzed retrospectively,and the imaging findings were compared with the pathologic findings.All data were analyzed by Fishersχ2 test.Re-sults 9 cases of presacral tumors were cystic type,18 cases were solid type and 10 cases were cystic-solid type.90.3% (28/31)of benign tumors had round or oval shapes,83.3% (5/6)of malignant tumors were irregular form(χ2=16.093,P=0.001).The den-sity of lesions whether uniform or not,and the presence of enhancement showed no obvious statistical differences between benign and malignant lesions.In all 37 cases,28 cases of benign and 1 case of malignant tumor were found compressed the surrounding tissues and organs;4 cases of benign and 5 cases of malignant tumor invaded adjacent tissues and organs(χ2=13.547,P=0.002).Conclu-sion CT and MRI can differentiate benign and malignant tumor,and can make clear diagnosis in some cases.
