Clinical question: Evaluate for headaches. Signs and symptoms: Headaches. Pre-and post-enhanced brain MRI:Unremarkable diffusion weighted images.There is normal anatomical morphology and with normal signal intensity of brain parenchyma on all MRI sequences.Unremarkable cerebral cortex, cortical sulci, ventricular system, CSF spaces and brain myelination.Anatomical variation of a small cavum septum pellucidum is noted. There is no detectable abnormal parenchymal, leptomeningeal or calvarial enhancement on post enhanced series.The signal void of major intracranial arterial branches are identified. The signal intensity of intracranial venous sinuses is within normal and with normal pattern of enhancement.Unremarkable images through the orbits including axial fat sat post enhanced series.All paranasal sinuses and bilateral mastoid air cells and middle cavities demonstrate normal pneumatization signal patterns.
