Aortopulmonary paraganglioma masquerading as an anterior mediastinal mass: A fine line between confusion and chaos!

Muhammad Usman Ali Shah et al. J Card Surg. 2020 Aug.

Abstract

Mediastinal paragangliomas are exceedingly rare neuroendocrine tumors of chromaffin cell origin. They are rarely endocrinologically functional, but complications often arise due to mass effect within the mediastinal cavity. We present a case of a 67-year-old gentleman referred to our unit for excision of a large mediastinal mass, thought to be thymic in origin, but without confirmatory preoperative histological diagnosis. Intra-operatively it became clear that the tumor was intra-pericardial, originating from aortic tissue, mandating pericardectomy, and ascending aortic replacement on cardiopulmonary bypass for its complete excision. Histopathological evaluation later confirmed the mass to be an aorticopulmonary paraganglioma.

Keywords: aorta and great vessels.
