 MRI Brain:There are multifocal small areas of restricted diffusion involving the bilateral right greater than left medial cerebellar hemispheres, left temporal lobe and right middle frontal lobe compatible with acute infarcts. There is no focal mass effect, hydrocephalus midline shift or herniation. Note that hemorrhage cannot be evaluated for on this exam. RIght frontal sinus mucosal thickening and partial opacification of the sphenoid sinuses.MRA Brain: Motion degradation limits full evaluation, especially involving the circle of Willis. Within these limitations, there is no gross stenosis involving the proximal ICA, MCA or ACA branches. There is the appearance of a focal stenosis involving the proximal left P2 segment. The vertebral arteries, basilar artery and right PCA are patent with no significant stenosis. No evidence of aneurysms or vascular malformations.
Only axial DWI and sagittal T1 sequences were obtained involving the brain MRI. Despite this limitation, multiple acute infarcts are seen involving the bilateral medial inferior cerebellar hemispheres, left temporal lobe and right middle frontal gyrus. There is no focal mass effect, hydrocephalus midline shift or herniation. Note that hemorrhage cannot be assessed on this exam.Limited MRA evaluation of the brain vasculature given extensive motion especially through the circle of Willis. Within these limitations there is the appearance of a focal stenosis involving the proximal left P2 segment. The remainder of the intracranial vasculature is grossly without significant flow limiting stenosis.
