Space-occupying Lesions

To this point, all disorders mentioned in association with CM-I have been congenital, but acquired methods of CM-I manifestation exist as well. This category includes both space-occupying lesions and CSF leaks. Space-occupying lesions within the posterior cranial fossa can be caused by a variety of disorders, ranging from brain tumors to hematomas. These can include supratentorial[45] and infratentorial[64] lesions. The multitude of potential spaceoccupying lesions is vast and thus beyond the scope of this review.
