Unspecified cerebral artery occlusion with cerebral infarction [434.91], Reason for Study: ^Reason: evaluate for acute stroke History: R droop, RUE weakness There is no evidence of acute ischemic or hemorrhagic lesion on the scan.On gradient echo images, there are multiple scattered focal signal voids on bilateral basal ganglia, temporal lobes and the left frontal lobe indicating age indeterminate likely chronic petechial hemorrhage or calcification.There are tissue losses likely represent chronic infarct on the pons, medulla, right frontal lobe and left corona radiata extending toward left internal capsule posterior limb.Underlying brain shows patchy high signal intensities on bilateral periventricular white matter indicate associated nonspecific small vessel ischemic disease.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, or restricted diffusion/acute ischemia. 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.
1. No evidence of acute ischemic or hemorrhagic lesion.2. Multifocal chronic ischemic infarcts with encephalomalacia on pons, medulla, right frontal lobe and left corona radiata as described above.3. Advanced nonspecific small vessel ischemic disease.
