Liver transplantation patient, altered mental status. No evidence of acute ischemic or hemorrhagic lesion.There is a focal high signal intensity on the left frontal lobe superior frontal gyrus subcortical white matter on FLAIR imaging which indicate age indeterminate ischemic lesion. Another focal tissue loss on the right cerebellar hemisphere is also seen which indicates chronic infarct.Bilateral basal ganglia signal intensities are normal.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.
No evidence of acute ischemic or hemorrhagic lesion.Chronic infarct with tissue loss, left frontal lobe and right cerebellar hemisphere.
