ABSTRACT

Diagnosis: Carotid Cavernous Fistula and ICA Aneurysm

History: 20 y/o male inside HUM-V when hit with an RPG (rocket propelled grenade).

Findings: CT with contrast shows an enlarged R parasellar region consistent with an ICA aneurysm, and abnormal vasculature filling with contrast in the R posterior fossa. The R Carotid angiogram shows a large, cavernous ICA aneurysm. The angiogram also shows that this aneurysm is draining into the cavernous sinus. The R superior opthalmic vein is engorged, and visible in the arterial phase. The carotid cavernous fistula is also draining posteriorly into the transverse and sigmoid sinuses (likely through the superior petrosal and inferior petrosal sinuses)which are also visible in the arterial phase of the angiogram.

Ddx: Trauma

Dxhow: Angiographic

No MeSH data available.


R internal carotid angiogram post-endovascular coiling of aneurysm.  There is no more engorgement of the superior opthalmic vein, the posterior venous drainage has been eliminated, and the transverse, and sigmoid sinuses are not filling in the arterial phase.
