Mediastinal paraganglioma irrigated by coronary vessels in a patient with an atypical chest pain.

We present a case of non-functioning anterior mediastinal paraganglioma in a 61-year-old woman. The tumour was accidentally discovered on a coronary angiography performed in an atypical precordial pain and dyspnea. The coronary angiography showed a vascular tumour in the paraaortic localization irrigated from two branches of coronary arteries. Diagnosis was confirmed by a thoracic tomographic scan which revealed an anterior mediastinal tumour. Complete tumour resection was done through a sternotomy with extracorporeal circulation without cardiac arrest. The histological examination of the operative specimen was characteristic of paraganglioma.
