  • Look Inside
  • Reference

A man in his seventies presented with vomiting and a large, sharply-marginated cystic mass behind the esophagus. Upon closer inspection, the cyst had an even density, and there was no solid lesion. First, we made a presumptive diagnosis of the cyst as a pericardial cyst or esophageal cyst. However, we finally diagnosed it as a mediastinal thoracic duct cyst based on lymphoscintigraphy. We performed 3-ports complete video-assisted thoracic surgery through the left thorax and carefully detached the cyst. Many lymph vessels were cut after clipping, and the cyst was excised completely. The patient had an uncomplicated postoperative course. We could perform 3-ports complete video-assisted thoracic surgery successfully because of the preoperative definite diagnosis. The case is reported with literature review.
