Thoracoscopic resection of a giant mediastinal parathyroid cyst.

Parathyroid cysts are a rare situation, unusually in the mediastinum. The preoperative diagnosis could be more difficult in some atypical topographies and imaging characteristics in particular in case of huge mediastinal cyst. In the following years traditionally, in case of intrathoracic parathyroid cysts, sternotomy or thoracotomy have been the preferred approaches. We report a case of an older patient with a huge mediastinal parathyroid cyst removed successfully using videothoracoscopy.
