Patient Data

Age: 45 years

MR reveals multiple tortuous and dilated vascular structures in the left cavernous sinus and asymmetrical dilatation of the left superior ophthalmic vein. Findings are suggestive of caroticocavernous fistula. 

There is also post-traumatic encephalomalacia at the left frontal and temporal lobes.

Case Discussion

Caroticocavernous fistulas are usually secondary to cranial trauma. In most cases, patients presenting with ipsilateral ocular pain increased intraocular pressure and proptosis.
