Evaluate for cause of seizure Exam is degraded by moderate motion artifact. Within this limitation following observations can be made:No focal parenchymal abnormality is appreciated. No cortical structural abnormality or gray matter heterotopia is identified. Hippocampus is symmetric in size and signal, and internal architecture is preserved. No abnormal diffusion restriction. No mass, mass effect, or midline shift. Ventricles and sulci appear normal without evidence of ventriculomegaly. No extra-axial fluid collection. No gross intracranial hemorrhage. There is suggestion of inferior cerebellar vermis hypoplasia with superimposed volume loss of the vermis and to a lesser degree cerebellar hemispheres. Paranasal sinuses and mastoid air cells are clear. Orbits are intact. Osseous structures are unremarkable. Major intracranial vasculature remains patent. No obvious focus of abnormal enhancement within the limits of significantly degraded postgadolinium sequences.
1. There is moderate degree of motion degradation on this study which limits evaluation for subtle abnormalities. Within this limitation, no findings to suggest seizure focus are appreciated. If there is high suspicion for a structural lesion, consider repeat examination with sedation.2. Cerebellar volume loss which may be related to chronic antiepileptic medication use.
