Clinical question: Daily headache. Signs and symptoms: Daily headaches. Nonenhanced brain MRI:Negative diffusion weighted images. Flair and T2-weighted images demonstrate 3 nonspecific punctate foci of hyperintensity in the right anterior frontal and left convexity frontal lobe.Unremarkable cerebral cortex, cortical sulci, ventricular system, CSF spaces and brain myelination otherwise.The signal voids of major intracranial arterial branches are identified. The signal intensity of intracranial venous sinuses are unremarkable.Unremarkable calvarium and soft tissues of the scalp.Unremarkable images through the orbits. All paranasal sinuses and bilateral mastoid air cells and middle ear cavities demonstrate normal pneumatization signal patterns.
Unremarkable nonenhanced brain MRI. Please see above comments.
