First time seizure. No findings to suggest seizure focus. No intracranial mass or mass-effect. No sulcation abnormality, heterotopic gray matter, or cortical dysplasia. Bilateral hippocampi are normal in size, signal characteristics, and demonstrate preserved internal architecture. No intracranial hemorrhage. No restricted diffusion to suggest acute ischemia. The ventricles are within normal limits in size and configuration. Low lying cerebellar tonsils which remain rounded with preserved adjacent subarachnoid spaces; no evidence of Chiari. Brain parenchyma is otherwise unremarkable for age.No abnormal parenchymal or meningeal enhancement. Major flow-voids are preserved.Sella and orbits are grossly within normal limits. Bone marrow signal and extracranial soft tissues are within normal limits.
1. No findings to suggest seizure fossa. 2. Low-lying tonsils cerebellar tonsils incidentally noted without convincing evidence of Chiari 1.
