title: Mediastinal paraganglioma fed by the left circumflex artery.
abstract: A 60-year-old male patient who previously underwent carotid and jugular paraganglioma resections was referred because of a mediastinal recurrence at the root of the great vessels. Coronary angiography confirmed the circumflex artery of the left coronary artery as the feeding artery of the tumour. The patient underwent surgery due to the tumour's location and malignant potential. Upon mass resection, histopathological examination characterized the tumour as a secondary paraganglioma. Neuroendocrine tumours arising from chromaffin tissues at the extra-adrenal paraganglions of the autonomic nervous system are termed paragangliomas. Clinically, they are divided into functional and non-functional types, depending on their catecholamine secretion. The mediastinal location is exceptional and its treatment is challenging.
