Case Report: Unilateral Cranial Nerve IV Palsy Secondary to Trochlear Schwannoma

CONCLUSIONS Although rare, schwannoma of the fourth cranial nerve should be considered in cases of cranial nerve IV palsies without an obvious etiology. Neuroimaging of the brain and orbits is warranted in cases where more common etiologies have been ruled out or when other cranial nerves and/or the brainstem are involved.
