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. |
