Clinical question: Evaluate lesion in right cerebellar hemisphere. Signs and symptoms: As above. Pre and post enhanced brain MRI:No diffusion-weighted abnormalities.Examination demonstratesTwo small wedge shaped foci of T2 hyperintensity and FLAIR hyperintensity in the right cerebellum which have the appearance of chronic right superior cerebellar artery territory ischemic strokes and unremarkable images through posterior fossa.Images of the supratentorial space demonstrate normal signal intensity and morphology of cerebral cortex, cortical sulci, ventricular system, CSF spaces and the brain myelination for age and without detectable abnormal enhancement.The signal void of major intracranial arterial branches are identified.The signal intensity of intracranial venous sinuses are within normal and with normal pattern of enhancement.Unremarkable calvarium and orbits without abnormal enhancement.All paranasal sinuses and bilateral mastoid air cells and middle ear cavities demonstrate normal pneumatization signal pattern.
1.No acute intracranial process.2.2 small wedge shaped foci of T2 hyperintensity in right posterior cerebellum although nonspecific they're highly suggestive of chronic strokes.3.Unremarkable pre and post enhanced brain MRI otherwise. Please see above comments.
