Thoracoscopic partial thymectomy for untraceable mediastinal parathyroid adenomas.

Despite accurate preoperative imaging, ectopic mediastinal parathyroid adenomas can be difficult to find via a thoracic approach.

We present the cases of three patients who were successfully cured using a thoracoscopic partial thymectomy.
