Bilateral Internal Carotid Aneurysms in the Petrous Temporal Bones

Giant petrous carotid aneurysm: persistent epistaxis despite internal carotid artery ligation

“…6 A differential diagnosis of glomus jugulare, glomus tympanicum, high jugular bulb, aberrant carotid artery and even persistent stapedial artery should be borne in mind. 6,7 In our patient, conventional angiography was performed in order to confirm the diagnosis, and was also used post-operatively as the patient still experienced minor symptoms despite surgical intervention.…”

Two stage management of petrositis with associated mycotic aneurysm of the intrapetrous carotid artery

“…Although aneurysms of the intrapetrous carotid artery include a differential diagnosis of glomus tumours, high jugular bulb or an aberrant internal carotid artery, 17 the evidence of petrositis, raised inflammatory markers and overall condition of the patient should alert the clinician to a mycotic aneurysm as the most likely diagnosis. A combination of CT, MRI and carotid angiography will confirm the diagnosis and the extent of the lesion.…”

An aneurysm of the petrous internal carotid artery

“…Aneurysms of the petrous portion of the internal carotid artery are rare, but should be part of the differential diagnosis of glomus jugulare, glomus tympanicum, high jugular bulb, aberrant carotid artery, or persistent stapedial artery (Moffat and O'Connor, 1980;Brandt et al, 1986). A combination of CT, MRI and magnetic resonance angiography (MRA) may be diagnostic, in particular MRI may be very suggestive of an aneurysm with the flow void and concentric rings of fresh thrombus and haemosiderin.…”
