Thoracic duct cyst of the mediastinum. A case report

There are only a few reports in the literature on cysts of the thoracic duct. This case report concerns a 56-year-old female patient, who was operated on because of a mediastinal mass that later proved to be a cyst of the thoracic duct. The operation and immediate postoperative course were uneventful. Six months later, the patient was doing well and no further investigations were recommended.
