“…Intrathoracic neurogenic tumors are usually localized at posterior mediastinum. They could arise either from the intercostal nerves or spinal nerve roots [ 1 , 5 , 7 ]. However, they may rarely arise from the nerve sheaths that are located in the intrabronchial, parenchymal, and middle or anterior mediastinal region [ 5 ].…”

Orki et al described a 43-year-old female patient that had left-sided chest pain for one month [ 5 ].

“…Most of these tumors are benign and with few or even no symptoms; thus, they are often detected by radiography or CT scanner incidentally [ 1 , 6 , 7 ]. Of these, schwannomas, the tumors sheathed with Schwan cells, and in phrenic nerve are very rare lesions that have sporadically been reported in few individual cases of literature [ 2 , 5 , 7 , 8 ]. We reported a case of asymptomatic schwannomas in the middle mediastinum originating from the right phrenic nerve.…”

Introduction. Neurogenic tumors in the mediastinum account for approximately 20-30% of all types of mediastinal tumors in adults. This pathology is usually benign and has no or very few symptoms. Schwannoma rarely involves the phrenic nerve. We report a unique case of schwannoma involvement of phrenic nerve. Case Presentation. The 43-year-old female patient has an annual check-up of computerized tomography to detect the mass in the right middle mediastinum, so the patient was admitted to the hospital. Chest computerized tomography image found a mass of the middle mediastinum with the size of 23 × 22.3 mm located between the right pulmonary artery and the pericardium with uniform margins and clear boundaries, not invading the surrounding organization. Very little contrast is absorbed after injection. She underwent a uniportal video-assisted thoracoscopic surgery, and this mass was found to be originating from the right phrenic nerve. Resection of the portion of phrenic nerve with mass was performed. Postoperatively, the patient was discharged from the hospital after 4 days of treatment in a clinical condition with no difficulty breathing and no chest pain; postoperative X-ray showed no abnormality, and the right diaphragm was unchanged. Conclusion. Although they are very rare, schwannomas of the phrenic nerve should be considered in the differential diagnosis of mediastinal tumors. Uniportal video-assisted thoracoscopic surgery is a preeminent option with properly sized tumors that deliver good results and have no postoperative complications associated with surgery.

Mediastinal masses of neuronal origin are exceedingly rare. We present the case of a 72-year-old woman, who was seen and evaluated by a pulmonologist, complaining of shortness of breath. The patient was found to have a mass visualized by computed tomography which was biopsied for pathologic identification. Upon microscopic examination of the transbronchial biopsy, neural tissue was observed. It is likely that the source of this ganglioma was of phrenic nerve origin.
