CT ANGIOGRAPHY OF THE HEAD

           

There is focal occlusion of the distal M2/proximal M3 branch of the left MCA with subtle delayed washout of the contrast in the left posterior parietal lobe. Remainder of the major intracranial arteries are patent with no mainstem/ major secondary branch occlusion or severe focal stenosis. 

The intracranial deep venous system and major dural venous sinuses demonstrate luminal contrast filling and appears  unremarkable. 

           

          

IMPRESSION: 

           

Focal occlusion of the distal M2/proximal M3 branch of the left MCA with subtle delayed washout in the left posterior parietal lobe. 

           

No definite ischemic changes demonstrated in the brain parenchyma.
