Clinical question: Migraine and episode suspicious of a seizure. Signs and symptoms: As above. Pre-and post-enhanced brain MRI:Negative diffusion weighted series.Examination demonstrates normal anatomical development of brain parenchyma without evidence of congenital anomaly.The signal intensity of brain parenchyma remains within normal in all MRI sequences.Unremarkable cerebral cortex, cortical sulci, ventricular system and CSF spaces and brain myelination.No detectable abnormal parenchymal, leptomeningeal or calvarial enhancement on post enhanced series.The signal voids of major intracranial arterial branches are identified. The signal intensity of intracranial venous sinuses is within normal and mid normal pattern of enhancement.Unremarkable images through the orbits including axial fat sat post enhanced studies. Extensive chronic maxillary sinusitis and minimally of other paranasal sinuses are noted. Bilateral mastoid air cells and middle ear cavities demonstrate normal pneumatization signal pattern.
Unremarkable pre-and post enhanced brain MRI.
