ABSTRACT

Diagnosis: Dural AV Fistulae

History: 48 yo woman with pulsatile tinnitus during exercise. Past surgical history includes craniotomy and repair of ruptured aneurysm.

Findings: Selective R and L internal carotid injections shows dilated anterior cerebral artery and early filling of anterior venous circulation. L ICA also has bilobed opthalmic artery aneursym. Venous phase of L ICA injection shows no filling of Superior Sagittal sinus which was partially obliterated during previous craniotomy. L ECA injection shows filling of superior sagittal sinus by middle meningeal artery. L ECA injection also shows retrograde flow through sinus with pathologic cortical venous drainage posteriorly i.e. cortical venous hypertension due to drainage of the fistula.

Ddx: AVM AV fistula

Dxhow: Angiographic diagnosis

No MeSH data available.


L ECA Injection, APview, shows rapid filling of superior saggital sinus secondary to AV fistula with the sinus and middle meningeal artery.
