Robot-assisted excision of ectopic mediastinal parathyroid adenoma.

Robot-assisted excision of an ectopic parathyroid adenoma in the superior mediastinum was performed in a 57-year-old man. The mass was located by methoxyisobutylisonitrile scan and computed tomography. Identification of the ectopic parathyroid adenoma was facilitated by the 3-dimensional images of the da Vinci robotic system, and resection was achieved using EndoWrist instruments. Robot-assisted excision of parathyroid adenoma located in the relatively inaccessible superior mediastinum proved to be feasible.
