5 years, Male, seizures. Sulcation and myelination appear within normal limits. No intracranial mass or mass effect. No midline shift or herniation. There are no diffusion or susceptibility abnormalities to suggest infarct or hemorrhage. No extra-axial collections. Ventricles and sulci are normal in size. There is T2 hyperintensity involving the anterior aspect of the superior frontal gyrus which almost entirely suppresses on the FLAIR sequence and favored to represent prominent perivascular space. Bilateral hippocampi are symmetric There is moderate mucosal thickening involving the left maxillary sinus and mild opacification involving the left ethmoid air cells. Calvarium and extracranial soft tissues are unremarkable.
No structural lesion to suggest seizure focus is definitively appreciated. There is small focus of T2/FLAIR hyperintensity involving the subcortical white matter in the right superior frontal gyrus, which is favored to represent a prominent perivascular space and less likely related to cortical dysplasia, but would suggest correlation with EEG findings. Examination is otherwise unremarkable.
