Abstract: Objective: To analyze the characteristics of mediastinoesophgeal fistulas Subsequent Esophageal Carcinoma after radiotherapy on multislice CT(MSCT),and evaluates the diagnostic value of MSCT.Methods: MSCT imaging of 10 patients who suffered with mediastinoesophgeal fistulas secondary to carcinoma of esophagus after radiotherapy were retrospectively studied.The CT scans involved axial computerized tomography and multi-plane reconstruction(MPR) and virtual bronchoscopy made on the workstation.The imaging manifestations were correlated with endoscope fingdings.Results: The CT imaging shows the fistulas successfully,and the mediastinitis were found in all the patents.The appearances of the fistula manifested on the bronchoscopy were consistent to the endoscope findings.Conclusion: MSCT and its virtual bronchoscopy are reliable for showing and assessing the mediastinoesophgeal fistula and its complications,thus afford a reliable imajings evidenced in proceed treatment.
