Why the study?
Aortic mural thrombi of the ascending aorta can cause fatal embolic complications, but reports of 4D-CT used to depict asymptomatic cases were lacking.
Case Report (n=1)
4D-CT is a useful and minimally invasive modality for evaluating the morphology and mobility of rare asymptomatic floating thrombi in the ascending aorta to guide timely surgical intervention.
May support 4D-CT for rare aortic thrombus evaluation; leaves open routine adoption pending prospective data.
Aortic mural thrombi of the ascending aorta are rare. If an aortic mural thrombus is dislodged, it can cause various embolic complications, which can sometimes be fatal. Although contrast-enhanced computed tomography (CT) and transesophageal echography are useful for diagnosing aortic mural thrombi, four-dimensional CT (4D-CT) is one of the most useful modalities for both diagnosis and treatment selection in such cases. 4D-CT can be used to evaluate the morphology and mobility of thrombi. Furthermore, it is minimally invasive. To the best of our knowledge, there have not been any reports about 4D-CT being used to depict an asymptomatic ascending aortic thrombus. We report a very unusual case, involving an aortic mural thrombus of the ascending aorta.

Nishimura et al. (2020) conducted a case report in Asymptomatic floating thrombus in the ascending aorta (n=1). Four-dimensional computed tomography (4D-CT) and ascending aorta replacement was evaluated on Diagnosis and treatment of aortic mural thrombus.
