We are not certain of the etiology or significance of this signal. This Image is through the inferior posterior fossa. . There are also multiple hyperintense nodules and lines along sulci at the bottom of the cerebellar hemispheres. None of these hyperintensities areas were present before contrast administration, thus these represent areas of enhancement. None of these hyperintense areas were present before contrast administration, thus they represent areas of enhancement.
Spinal involvement is unusual.
CNS involvement is one of the more common causes of sarcoid related mortaliy. Enhanced MR imaging has been shown to be effective in demonstrating CNS lesions. Due to inflammation of the meninges resulting in extraventricular obstruction or intraventricular obstruction. Most common finding. Most commonly basal.
