 MRI brain: Again seen are multiple supratentorial T2/FLAIR hyperintense lesions involving the subcortical and periventricular white matter, including callososeptal interface, grossly unchanged since 8/23/2014. Some of the lesions demonstrate corresponding T1 hypointensity. There is no enhancement associated with any of these lesions. There are no new lesions in the brain parenchyma.The ventricles and sulci are within normal limits. The cisterns remain patent. There is no midline shift or mass effect. There is no diffusion abnormality. No extra-axial fluid collection is identified.Normal flow-voids are demonstrated in the major intracranial vascular structures. The midline structures and craniocervical junction are within normal limits.MRI cervical spine: There is a patchy area of increased T2 signal abnormality in the right lateral aspect of the cervical cord at C2 level, progressed compared to 1/7/2011. There is a stable tiny focus of increased T2 signal abnormality at C1, unchanged from prior. There are patchy areas of increased signal intensity within the cervical cord extending from C3 to C4 bilaterally which are slightly progressed since the prior exam from 1/7/2011. No definite enhancement is appreciated corresponding to the lesions in the cervical cord. No new lesions in the cervical cord.The cervical spine is in normal alignment, with a normal cervical lordosis. The vertebral body and disk heights are well-maintained. No worrisome focal marrow signal abnormality is appreciated. There is no significant disk bulge, herniation, spinal canal or foraminal stenosis within the cervical spine. MRI thoracic spine: There are multiple areas of patchy increased signal intensity within the thoracic cord at T3, T4-T6, T9, T10 and T11, similar to prior. No evidence of abnormal enhancement or new lesions are seen in the thoracic cord.The thoracic spine is in normal alignment, with a normal thoracic kyphosis. The vertebral body and disk heights are well maintained. No worrisome focal marrow signal abnormality is appreciated. There is no pathological enhancement.There is no significant disk bulge, herniation, spinal canal or foraminal stenosis within the thoracic spine.
1. Multiple T2/FLAIR hyperintense lesions in the brain consistent with known demyelinating disease. Compared to 8/23/2014 no new lesions are seen. No lesions with enhancement to suggest active demyelination.2. Patchy T2 hyperintensity involving the cervical cord appears slightly increased at the C2 and C3-C4 levels when compared to MRI dated 1/7/2011. No definite enhancement to suggest active demyelination.3. Patchy areas of demyelinating plaques throughout the thoracic cord with no enhancing lesions, not significantly changed since MRI dated 1/7/2011.
