Petroclival meningioma arises in the upper two thirds of the
clivus at the petroclival junction medial to the fifth cranial nerve. These tumors displace the brain stem and the basilar artery to the
opposite side. Petroclival meningiomas are surgically challenging tumors due to
the proximity to cranial nerves, major blood vessels, and the brainstem with
considerably high postoperative morbidity and mortality. Patients usually
present with insidious onset of headache, lower cranial neuropathy with unilateral
hearing loss or facial sensory disturbances may be the most frequently
encountered and in severe cases, trigeminal neuralgia. Brainstem and
cerebellar compression signs e.g. gait disturbance are not uncommon. Gamma Knife
surgery of petro-clival meningiomas is the treatment of choice.
