Vascular Diverticulum and Aneurysm: A Comment on Usage of Correct Terminology
Journal Title: American Journal of Interventional Radiology - Year 2018, Vol 2, Issue 7
Abstract
We recently encountered two patients in whom imaging revealed vascular outpouchings. One, a middle-aged male, had a cone-shaped outpouching arising at the junction of the aortic arch and the descending thoracic aorta suggestive of ductus diverticulum. While "aneurysm" and "diverticulum" have both been described in relation to ductus arteriosus (DA), one also encounters the confusing term "aneurysm of the ductus diverticulum". Another patient being evaluated for pulsatile tinnitus had a soft tissue projecting into mastoid air cells through a defect in the sigmoid plate of temporal bone and an outpouching of sigmoid sinus corresponding to the same location. This entity has been variously described in literature as "venous sinus diverticulum" and "venous sinus aneurysm".
