history of breast cancer, stroke on the right hemisphere. There are restricted diffusion lesion on the right pre central gyrus extending to the level of frontal operculum indicating acute ischemic infarction. There is no evidence of hemorrhagic conversion.On post gadolinium scan, those involved right frontal lesions show cortical and subcortical enhancement indicating subacute ischemic infarction.There is no other abnormal enhancement on this scan.The ventricles, sulci and cisterns are symmetric and unremarkable. There is no mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage. The midline structures and cranial-cervical junction are normal. The paranasal sinuses and mastoid air cells are clear.3D time of flight MOTSA MRA brain images with maximum intensity projections of the anterior/posterior intracranial circulation demonstrate relatively sparse right MCA branches especially frontal lobe area, however, no definitive evidence of large vessel occlusion or stenosis.Left MCA and bilateral ACAs appear to be normal.Vertebrobasilar system appears to be normal.There is no evidence of intracranial arterial aneurysm.3D MRA neck post-gadolinium images with maximum intensity projections of the cervical vasculature demonstrate normal flow enhancement in a normal aortic arch origin of the right brachiocephalic, left common carotid, and left subclavian arteries. The vertebral artery origins are normal. There is normal flow enhancement through the bilateral common carotid, carotid bifurcations, internal/external carotid, and vertebral arteries.
1. Acute ischemic infarction on the right frontal lobe pre central gyrus as described above. No hemorrhagic conversion.2. Sparse right MCA branches on the right frontal lobe area, otherwise unremarkable brain MRA3. Normal neck MRA4. No abnormal enhancement except acute/subacute ischemic infarction area enhancement.
