Male, 19 years old, behavioral abnormality is hyperactivity, memory problems, assess for progression of toxic leukoencephalopathy/ADEM. Image quality is degraded by motion artifact. In addition, several standard sequences were not obtained including FLAIR and susceptibility weighted imaging as the patient requested to abort the examination early. Within these limitation, the following observations are made.Extensive signal abnormality seen on the prior examination involving the basal ganglia, insulae, midbrain and pons seems to have largely resolved. Some residual signal abnormality in these areas is possible, given the poor quality of the images, but if anything it is mild.No evidence of significant mass effect seen. No abnormal extra-axial collections are detected. Ventricles are normal in size and morphology. No restricted diffusion is seen.
Limited examination due to patient motion and to early termination of the study at the patient's request.Extensive signal abnormality seen on the prior examination involving the bilateral basal ganglia, insulae, midbrain and pons has largely resolved. At most there may be minimal residual signal abnormality in these areas.No evidence of restricted diffusion, mass effect, or any pathologic fluid collections are seen.
