Female, 17 years old, localization-related (focal) (partial) idiopathic epilepsy and epileptic syndromes with seizures of localized onset, not intractable, without status epilepticus. Previous imaging and EEGs at Lurie Children's Hospital. No restricted diffusion to suggest acute ischemia. No intracranial hemorrhage. No intracranial mass or mass-effect. The ventricles are within normal limits in size and configuration. No gray matter heterotopia or cortical dysplasia is evident. There are three or four very small nonspecific foci of T2/FLAIR hyperintensity in the subcortical white of the left cerebral hemisphere. Brain parenchymal signal is otherwise unremarkable. The mesial temporal lobe structures are symmetric and free of signal abnormality.Major flow-voids are preserved on T2 sequences. Sella and orbits are grossly within normal limits. Paranasal sinuses and mastoid cells are clear. Bone marrow signal and extracranial soft tissues are within normal limits.
No MRI findings to account for the patient's seizures. There are a few scattered foci of increased T2/FLAIR signal in the subcortical white matter of the left cerebral hemisphere, which are nonspecific. Correlation with prior outside imaging may be beneficial.
