RESUMO
Mediastinal paragangliomas are very uncommon neuroendocrine neoplasms. Due to their tissue of origin (sympathetic ganglia of the great vessels), they tend to arise deep within pericardial space and, more importantly, intimately attached to great vessels, which makes surgical resection, even with cardiopulmonary bypass, very challenging. This commentary accompanies the case report describing complex surgical management of a paraganglioma located in the anterior mediastinum that was initially thought to be a thymoma.

Acute type A thoracic aortic dissection is a life-threatening condition that requires rapid diagnosis and prompt surgical intervention. Prior cardiac surgery is recognized as a predisposing risk factor. Here, we report a rare case and successful surgical repair of a late presenting acute type A thoracic aortic dissection four years after a three-vessel coronary artery bypass grafting. Resection of the aortic valve and aneurysmal tissue was required, reconstruction was done with a composite graft, and the native coronary ostia and aorto-saphenous buttons were preserved.
