Authoring team

Parasagittal meningiomas tend to irritate and compress the areas of the primary motor and sensory cortex concerned with lower limb function.

Features include:

  • seizures or pyramidal weakness in the leg which may progress to bilateral leg weakness if the lesion extends through the falx

  • homonymous hemianopias from posterior parasaggital lesions

  • impairment of memory, intellect and personality from anterior parasagittal tumours, which may progress to dementia
