Cerebral infarction, unspecified [I63.9], Reason for Study: ^Reason: stroke workup History: left sided weakness, dysphagia, slurred speech The examination is limited secondary to extensive motion artifact. There is a confluent area of encephalomalacia and gliosis in the right paramedian parietal lobe, cingulate gyrus, medial temporal lobe, and occipital lobe. There is associated ex vacuo dilatation of the right lateral ventricle. There are also small areas of encephalomalacia in the left basal ganglia and corona radiata with ex vacuo dilatation of the frontal horn. There is a background of scattered cerebral white matter T2 hyperintensity. There is a new area of T2/FLAIR hyperintensity involving the right thalamus and paramedian right midbrain. There is no evidence of acute ischemia. There are no masses, mass effect or midline shift. The skull, paranasal sinuses, and mastoid air cells are unremarkable.
1. No evidence for acute ischemia.2. Right PCA territory encephalomalacia with chronic infarcts in the left basal ganglia and corona radiata superimposed upon a background of small vessel ischemic disease, similar to prior examination.3. A focus of T2/FLAIR hyperintensity involving the right thalamus and right paramedian midbrain appears new since prior examination and may relate to interval area of now subacute ischemia since prior MRI from 7/5/2016.3. MRA and MRV could not be obtained due to patient's inability to tolerate the examination.
