Clinical question: Seizure-like activity. Signs and symptoms: As above. Nonenhanced brain MRI:Examination demonstrate normal anatomical development of brain and a normal pattern of myelination for age.There is no detectable cortical abnormality. The cortical sulci remain within normal. The ventricular system remain within normal size and morphology for age and with maintained midline.Signal void of all major intracranial arterial branches are identified.The signal intensity of the intracranial venous sinuses appear normal. Unremarkable images through the orbits.The signal intensity calvarium demonstrate no abnormalities.Images through the paranasal sinuses and bilateral mastoid air cells demonstrate diffuse increased T2 signal intensity.
1.Unremarkable nonenhanced brain MRI for age.2.Diffuse patchy opacification of mastoid air cells and paranasal sinuses.
