 Brain: Motion artifact somewhat limits evaluation. There are approximately fiveT2/FLAIR hyperintense lesions involving the periventricular and subcortical white matter compatible with known demyelinating disease. These lesions include a juxtacortical lesion involving the left superior frontal gyrus and periventricular lesions adjacent to the left frontal horn and atria of the bilateral lateral ventricles. There is T1 hypointensity associated with the right parietal lesion. No intracranial mass or mass effect. There is minimal global parenchymal volume loss for age. Thoracic Spine: There are multiple T2 hyperintense lesions throughout the thoracic cord consistent with known demyelinating disease. These lesions are best seen on the sagittal T2 and STIR sequences and include T1-T2, T3-T4, T4-T5, T6, T8, T9, and T10 levels. The right dorsal T1-T2 lesion is associated with mild volume loss similar to prior. At least majority if not all of the remainder of the lesions are present on prior study but more apparent on the current study likely due to differences in technique, and perhaps evolution of the lesions. The thoracic spine is in normal alignment. 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 thoracic spine.
1. Approximately 5 T2/FLAIR hyperintense lesions in the supratentorial white matter consistent with known demyelinating disease. No prior brain MRI is available for comparison. Addendum can be issued if prior imaging is made available.2. Multiple T2 hyperintense lesions throughout the thoracic cord consistent with demyelinating disease. Prior thoracic spine MRI study was limited due to artifact however in retrospect, the lesions identified on the current study appear to be present (although more subtle) on the prior study. As such there is no convincing evidence of progression of demyelinating disease in the thoracic cord.
