Saccular Kommerell aneurysm, a potential pitfall on MDCT imaging – A review of imaging features and potential mimics

Publication date: 2017Source: European Journal of Radiology Open, Volume 4Author(s): Hui Lin Wong, Charlene Jin Yee Liew, Angeline Choo Choo PohAbstractSaccular Kommerell aneurysm represents a potential pitfall on Multidetector CT (MDCT) imaging, mimicking conditions such as saccular aneurysm of the thoracic aorta, ductus diverticulum and dilated Kommerell diverticulum. Accurate diagnosis of this condition is critical in the management of this potentially fatal condition. This paper reviews the MDCT imaging features of Kommerell aneurysms and its mimics and demonstrates how to make an accurate diagnosis through a series of four cases. MDCT features of Kommerell aneurysms, either saccular or fusiform types arising from a Kommerell diverticulum with atherosclerotic plaque and mural thrombus are discussed.
