Abstract
BackgroundRobot-assisted thoracoscopic surgery (RATS) is useful for surgery in the apical region of the chest cavity, as it narrows towards the head. Here, we describe a nonfunctional, rib-invasive paraganglioma arising in the posterior mediastinum that was successfully removed using RATS combined with chest wall resection.Case presentationA 31-year-old woman presented with a posterior mediastinal mass on chest computed tomography (CT) scan during a medical check-up 2 years prior. Positron emission tomography/computed tomography scan with F-18 fluorodeoxyglucose revealed a mass associated with standardized uptake maximum value of 2.69. With a preoperative diagnosis of neurogenic tumor by CT-guided percutaneous fine-needle aspiration biopsy, we performed robot-assisted tumor resection combined with chest wall resection. The wristed instruments of the robotic surgical system have increased range of motion and enabled the tumor resection without organ injury in the thoracic cavity. Histopathology examination revealed a non-functional paraganglioma with rib invasion.ConclusionsRATS is a useful technique, enabling safer and easier resection of a mediastinal tumor adjacent to surrounding organs.

Mediastinal paragangliomas are rare tumors that arise from extra-adrenal paraganglionic cells of the sympathetic nerve system; they are commonly known as pheochromocytomas
To the best of our knowledge, this is the first reported use of RATS for a posterior mediastinal tumor combined with chest wall resection
