Clinical question: Migraine for the last 6 months. Signs and symptoms: Migraine for the last 6 months. Pre-and post-enhanced brain MRI:Diffusion weighted series are unremarkable.The anatomical morphology as well as the signal intensity of brain parenchymal remains within normal on all MRI sequences.Unremarkable cerebral cortex, cortical sulci, ventricular system, CSF spaces and myelination of brain.The signal void of major intracranial arterial branches are identified.The signal intensity of intracranial venous sinuses is within normal.Post enhanced images demonstrate no detectable abnormal enhancement of brain parenchyma, leptomeninges, calvarial or the retro-orbital spaces.All paranasal sinuses and bilateral mastoid air cells and middle ear cavities demonstrate normal pneumatization signal intensity.
1.Negative pre-and post enhanced brain MRI.2.Unremarkable calvarium, well pneumatized paranasal sinuses, mastoid air cells and middle ear cavities.
