Cerebral infarction due to unspecified occlusion or stenosis of left middle cerebral artery [I63.512], Reason for Study: ^Reason: evaluate for stroke extension History: as above Brain MRIThere is no evidence of acute ischemic stroke on the scan.Previously seen left MCA territorial ischemic stroke demonstrate usual evolution weight multifocal susceptibility lesions indicating hemorrhagic conversion. There is no evidence of mass effect.There is interval development of subdural hematoma along the right temporo-parieto-occipital lobe.The ventricles, sulci and cisterns are unremarkable. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.Brain MRA3D time of flight MOTSA MRA brain images with maximum intensity projections of the anterior/posterior intracranial circulation demonstrate severe (based on MRA, it appears to be close to more than 90%) luminal stenosis at the proximal left MCA M1 segment, unchanged.Other intracranial vascular structures appear to be normal.
1. No acute ischemic lesion.2. Normal evolution of left MCA territorial ischemic stroke with multifocal hemorrhagic conversion lesions.3. Interval development of the right temporo-parieto-occipital subdural hematoma.4. Unchanged high grade left MCA proximal M1 segment stenosis.
