Clinical question: Infection/inflammation? Signs and symptoms: Acute cerebellar signs. Pre- and post enhanced brain MRI:Diffusion weighted images are degraded due to extensive metallic artifact in particular in the posterior fossa. Beyond the region of artifact no detectable acute ischemic change is noted.Examination demonstrate normal anatomical development/morphology of brain parenchymal and with normal signal intensity on all MRI sequences.Unremarkable cerebral cortex, cortical sulci, ventricular system, CSF spaces and brain myelination for age.Signal void of major intracranial arterial branches are identified.There is no detectable abnormal parenchymal, meningeal or calvarial enhancement. Note however should be made that the inferior aspect of cerebellum is obscured by metallic artifact and cannot be assessed.Unremarkable images through the orbits and including axial fat sat post enhanced series.The signal intensity of the intracranial venous sinuses are within normal.Unremarkable calvarium and soft tissues of the scalp.Unremarkable images through the paranasal sinuses and mastoid air cells.Nonenhanced total spine MRI:Examination is performed utilizing cord compression protocol.Examination demonstrate normal anatomical development of vertebral column.There is normal anatomical alignment and signal intensity of vertebral column.There is no evidence of spinal canal or neural foraminal compromise or stenosis at any level.There is normal signal intensity and caliber of the cord, conus and the cauda equina.No detectable paraspinal soft tissue abnormalities.
