Case report of a peculiar aneurysm of the ascending aorta: when there is much more beyond an incidental finding

Aneurysms of the thoracic aorta are common in male patients around the VI–VII decade of life and most have a degenerative aetiology; otherwise, the occurrence of this disease at a younger age should prompt the search of rarer causes. We report a singular case of ascending aortic aneurysm (AAA) in a young man.

A large AAA accompanied by multivessel dilatation and renal failure of unknown onset was incidentally found in a 23-year-old male during the diagnostic work-up after a car accident. A systemic disease was therefore suspected, and a full clinical investigation revealed the uncommon diagnosis of sarcoidosis accompanied by large vessel vasculitis.

Only a few reports in the literature describe the concurrence of sarcoidosis and large vessel vasculitis (Takayasu arteritis), which may share non-specific immunoinflammatory abnormalities. This case underlines the importance of a multisystem diagnostic approach even in front of an incidental finding that is inconsistent with patient’s age.
