Surgery for a suspected mediastinal tumor reveals a large thrombosed right sinus of Valsalva aneurysm.
Case Report (n=1)
A thrombosed saccular aneurysm of the sinus of Valsalva can present unusually as a mediastinal mass mimicking a tumor on imaging.
Warrants including sinus of Valsalva aneurysm in mediastinal mass differentials; case report leaves open standardized diagnostic algorithms.
A 33 year old man presented with a short history of slight fever and chest pain that was worse on inspiration. An electrocardiogram was consistent with pericarditis. Chest radiography, echocardiography, and computed tomography suggested the presence of a mediastinal tumour. At operation the mass was found to be attached to the right sinus of Valsalva and proved to be a large saccular aneurysm full of laminated thrombus.

Reid et al. (1990) conducted a case report in Thrombosed saccular aneurysm of a sinus of Valsalva (n=1). Surgical exploration was evaluated on Operative findings. Surgical exploration of a suspected mediastinal tumor in a 33-year-old man revealed a large saccular aneurysm of the right sinus of Valsalva filled with laminated thrombus.
