 Encephalomalacia with gliosis and a rim of susceptibility hypointensity is present involving the posterior right frontal lobe (precentral gyrus). There is no associated restricted diffusion or enhancement.There are scattered punctate foci of T2 hyperintensity within periventricular and subcortical white matter without restricted diffusion, mass effect, or enhancement.The ventricles and sulci are normal in size. The cerebellar tonsils are in normal position. There are no masses, mass effect or midline shift. The pituitary gland is normal in size. There is no evidence for intracranial hemorrhage or acute cerebral, brainstem or cerebellar infarction. No diffusion-weighted abnormalities are identified. There are no extraaxial fluid collections or subdural hematomas. Flow voids are present within the major vessels indicating patency. Mucosal thickening is present within posterior right ethmoid air cells and the left sphenoid sinus. The remaining paranasal sinuses and mastoid air cells are clear. There is no abnormal enhancement within the brain.
1.Remote right MCA territory infarct.2.Mild chronic small vessel ischemic disease.3.No MRI evidence of metastatic disease.
