This film presents the case of an 85-year-old man who suffered from primary hyperparathyroidism diagnosed on a pathological cervical fracture and elevated laboratory values for parathyroid hormone and calcium. Preoperative localizing studies showed no anomalies on the parathyroid gland. However, a left anterior mediastinal ectopic parathyroid adenoma was found on 99m Tc-MIBI scintigraphy. Mediastinal parathyroid adenomas can be resected in a minimally invasive fashion via a conventional transcervical approach, or using a video-assisted thoracoscopic resection, allowing for an access to the lower cervical area without the use of a cervicotomy. Robotic-assisted thoracic surgery (RATS) also allows for a better visualization and less instrument crowding, with no difference in clinical results. Considering the good efficacy and the better chances not to leave tumor tissue missed out during surgery, and the impossibility to install the patient with cervical hyperextension, we decided to perform a robot-assisted thoracoscopy through a left-sided approach, instead of the conventional transcervical approach. During the intraoperative period, the adenoma was identified, and we did not feel the need to perform PTH assay. There were no complications in the postoperative period. PTH levels reached a normal range after adenoma removal, and the patient was discharged on postoperative day 3. He remains asymptomatic at 3 months after the intervention. The robotic resection of an intrathymic parathyroid adenoma is a safe and effective alternative to the conventional transcervical approach.
