Clinical question: Upstroke. Signs and symptoms: Confusion, history of stroke. Nonenhanced brain MRI:There is no evidence an acute intracranial process and including acute stroke.There are subtle ill-defined foci of flair hyperintensity in the pons bilaterally. Findings are nonspecific however in the proper clinical setting this appearance could represent microvascular ischemic changes.Unremarkable cerebral cortex, cortical sulci, ventricular system, CSF spaces and myelination the brain otherwise.The signal void of major intracranial arterial branches are identified.The signal intensity of intracranial venous sinuses are within normal.Unremarkable calvarium, soft tissues of the scalp, and orbits, paranasal sinuses and mastoid air cells.
1.No acute intracranial process.2.Subtle ill-defined foci of flair hyperintensity in pons which could represent microvascular chronic ischemic change and unremarkable nonenhanced brain MRI otherwise.
