Diplopia resolved, evaluate for new lesions compared to 12/2014. Again seen are greater than 20 foci of T2/FLAIR hyperintensity in the bilateral periventricular and subcortical white matter. No new lesions compared to 12/5/2014 are appreciated. No intracranial mass or mass effect. No evidence of acute ischemia or hemorrhage. No hydrocephalus. No extra-axial collections. Brain parenchymal volume is preserved. Mucous retention cysts in the maxillary sinuses, right larger than left, again seen and unchanged. Major flow-voids are preserved. Bone marrow signal is within normal limits.
Multiple T2/FLAIR hyperintense lesions in the periventricular and subcortical white matter are compatible with known demyelinating disease. No new lesions compared to 12/5/2014 are appreciated.
