Clinical question: Cerebellar disease showing marked signs and symptoms: Staggering gait. Pre and post enhanced brain MRI:Negative diffusion weighted series.Images through posterior fossa demonstrate mild prominence of cerebellar and vermian folia which may stable be within normal range for patient's stated age of 56.Images through supratentorial space demonstrate few tiny nonspecific foci of subcortical and periventricular FLAIR hyperintensity in bilateral frontal lobes and unremarkable otherwise.Unremarkable cerebral cortex, cortical sulci, ventricular system and CSF spaces.No detectable abnormal parenchymal, leptomeningeal or calvarial enhancement.Unremarkable images through the orbits and including axial fat sat post enhanced series.Normal signal intensity of intracranial venous sinuses and with normal pattern of enhancement.Normal signal intensity of the visualized paranasal sinuses and mastoid air cells.
1.No acute intracranial process and negative diffusion weighted series.2.A few punctate nonspecific FLAIR hyperintensity in bilateral frontal subcortical and periventricular white matter.3.Slight prominence of cerebellar and vermian folia which may be at the upper limits of normal and unremarkable pre and postcontrast enhanced study otherwise.
