 Limited sequences per demyelinating disease protocol. Again seen are multiple T2/FLAIR hyperintense lesions in the periventricular and subcortical supratentorial white matter with morphology and distribution consistent with known demyelinating disease. Multiple brainstem and cerebellar lesions are also again seen, which are predominately along the dorsal midbrain and pons similar to prior. No new lesions are identified. Mild to moderate burden of T1 hypointense lesions again seen similar to prior. Mild parenchymal volume loss including mild thinning of the corpus callosum similar to prior. No evidence of intracranial mass effect, midline shift, or herniation.
Compared to 5/22/2015, there are no new lesions in the brain to suggest progression of demyelinating disease.
