Mediastinal paragangliomas are unusual neoplasms that have been described in the medical literature. The microscopic features of paragangliomas are well established and are essentially similar, regardless of the anatomic site, although some minor differences have been noted according to the location of the tumor. We present a case of nonfunctioning anterior mediastinal paraganglioma in a 33-year-old woman. The mediastinal tumor was accidentally discovered on a thoracic tomographic scan performed for an unrelated minor nasal discomfort. Diagnosis was confirmed by 123l-metaiodobenzylguanidine scintigraphy and mediastinoscopy. Complete resection of the tumor was done through a median sternotomy and the patient received intraoperative radiotherapy.
