ResultsFour cases are huge mass of solid oval with integrity of coat and smooth, clear edge; they grow at the right middle or right posterior inferior mediastinum, along the spine, no expansion of intervertebral foramen and down to enter into crura of diaphragm; their density are less uniform, in two masses with a sand calcification image. In plain scanning, the CT values is 23~33Hu; in dynamic state enhancement scanning of 4 cases the mass are not enhanced or not obviously strengthened at arterial phase, and have a linear strengthen at venous phase.

In treatment group, 42 cases received 50 Gy radiation, at 2 Gy per day, 5 d per week in the upper mediastinum, hilus of lung, below the primary focus first and then underwent X-knife for the primary focuses, and other 14 recurrent and metastatic cases received irradiation of 8-12 Gy per day, 5 d by X-knife alone.

治疗组中42例为外照射上纵隔、同侧肺门、隆突下及原发灶50 Gy/25F后加用X线刀治疗原发灶5 Gy/次×5次；14例为肺转移癌或手术后外周孤立性复发病灶行单纯立体定向放射治疗，8～12 Gy/次×5次。

The fistula could be diagnosed correctly when the patient suffered high fever, dyspnea and thoracalgia after operation, with cervical anastomotic external fistula which could not been healed when the wound was opened, X-ray-showed widened mediastinum and hydropneumothorax, and drainage, esophagoraphy and CT-confirmed anastomotic fistula.
