[Thoracoscopic resection of a voluminous dermoid cyst of the mediastinum, using a 3-dimensional imaging system]

A case of a young patient who was operated on of a large dermoid cyst of the anterior mediastinum is reported. During this procedure, a new three-dimensional imaging system was used. This case-report confirms the usefulness of thoracoscopy for benign mediastinal tumors removal and points out the benefit of three-dimensional endoscopy for dissection of tumors having complex anatomical connections.
