 There is a focus of restricted diffusion in the splenium of the corpus callosum with associated T2/FLAIR hyperintensity.Elsewhere there is no significant signal abnormality or evidence of edema or mass effect. The cerebellar tonsils remain above the foramen magnum. There is no grey matter heterotopia, cortical dysplasia or evidence of mesial temporal sclerosis. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The skull and extracranial soft tissues are unremarkable. The cervical spine demonstrates slight enlargement of the central canal at the level of C5-C6 with a diameter of no more than 1 mm. Otherwise, the cervical and the thoracic spine is normal. In the lumbar spine there is a focus of high T1 signal from the level of L4 to the level of L5 at midline along the posterior thecal sac that could represent fibrofatty infiltration of the filum terminale. The conus medullaris ends at the level of L1. Normal marrow signal of the vertebral bodies. There are no structural abnormalities.
1. Restricted diffusion in the splenium of the corpus callosum associated with T2/FLAIR hyperintensity. This likely represents cytotoxic edema related to seizure activity and/or the effect of anti-seizure medication.2. Findings suggestive of a short segment of fibrofatty infiltration of the filum terminale. In the absence of other findings of tethered cord, this can be an incidental finding. Correlation with clinical symptoms is suggested.3. The remained of the spine exam is within normal limits.
