parasagittal meningioma

Last reviewed 01/2018

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
