Fabio Robert et al in his study about posterior fossa meningioma reported that headache (50%) and disturbance of gait (44%) were the most common presenting symptoms, and cranial neuropathies the most common neurological signs on admission.
Symptoms of meningioma can be caused by the tumor pressing on the brain or spinal cord, stopping the normal functioning of a specific part of the brain, or pressing on nearby nerves or blood vessels. If the meningioma involves nearby bone, it may cause the bone to expand.
