We conclude that an aneurysm of the petrous carotid artery should be included in the differential diagnosis of cases presenting with a cavernous sinus syndrome. The aneurysm is within the carotid canal and is associated with parent artery stenosis. Petrous carotid aneurysms can produce a wide clinical spectrum of signs and symptoms in younger patients; these aneurysms frequently are fusiform and contain chronic thrombus.

We will address aneurysms arising at these locations individually. Early diagnosis followed by definitive treatment is important for the alleviation of clinical symptoms associated with this lesion. The risk of rupture is higher than the rupture risk of a true aneurysm [3]. The presence of such an aneurysm may be easily confirmed by angiographic study, averting the possibility of an ill-advised surgical procedure. Computed tomography angiography demonstrated a giant petrous carotid aneurysm and erosion of a part of the left temporal bone. With the help of intervention from radiologist, a right internal carotid artery (ICA) trapping was done using coil embolization under guidance of intraoperative angiography [Figure 3] a … Figure 4. my of the petrous ICA as well as the pathophysiological features of aneurysms arising in this region, and they propose a management paradigm with current treatment options.
