Male, 57 years old, with right leg weakness. Assess for hemispheric lesion. A small wedge-shaped region of encephalomalacia is evident along the inferior right cerebellar hemisphere, unchanged from prior. A few scattered punctate foci of white matter T2 hyperintensity are also evident in the cerebral hemispheres, not significantly changed.No evidence of restricted diffusion is seen. No parenchymal edema or mass effect is detected. There are no findings to suggest intracranial hemorrhage or any other abnormal extra-axial fluid collection. The ventricular system is patent and normal in size.
1.Evidence of a small chronic right PICA distribution infarct.2.Several scattered punctate foci of white matter T2 hyperintensity are nonspecific and probably not significantly changed.3.No evidence of acute ischemia, mass or mass effect, or other acute intracranial abnormality to account for the patient's symptoms.
