Early diagnostic value of multi-slice spiral CT for cystic mediastinal tumor / 中国基层医药

ABSTRACT

Objective To evaluate the value of multi-slice spiral CT in the early diagnosis of cystic mediastinal tumors.Methods 60 cases with cystic mediastinal tumor were collected.All patients were examined by multi-slice spiral CT,and the CT findings of all patients with various types of mediastinal tumors were statistically detected.Results (1) CT manifestations of thymic cyst showed clear boundary of the circular or oval or triangular mass,thin cyst wall,uniform density,internal watery density,no enhancement,the diagnostic accuracy rate was 90.48％.(2)CT manifestations of thymoma sac variable showed round or oval,cystic wall smooth,uniform density of the inner edge of the center for low density cystic variable.Enhanced scan showed uniform or mild enhancement of the inhomogeneous enhancement,the diagnostic accuracy rate was 93.75％.(3)CT manifestations of teratoma showed round and similar to the round or irregular in shape,the thickness of cystic wall,fuzzy edge,different density,enhancement,the diagnostic accuracy rate was 100.00％.(4)CT manifestations of bronchogenic cyst showed round or oval mass,clear boundary,thickness of cystic wall,uniform density,internal watery density,cyst wall strengthening,lesions no enhancement,the diagnostic accuracy rate was 90.00％.Conclusion Cystic mediastinal tumors can be diagnosed by CT,which has guiding significance for clinical.
