title: Ocular tilt reaction due to a cerebellar hemorrhage.
abstract: A 78-year-old man with essential hypertension abruptly developed complete ocular tilt reaction (OTR) which consisted of concomitant skew deviation with left hypertropia, extorsion of the right eye and intorsion of the left, and rightward head tilt. Cranial computed tomography demonstrated a localized cerebellar hemorrhage involving the left nodulus. The patient became asymptomatic within two weeks. This is a first reported case of complete OTR due to a cerebellar hemorrhage. Concomitant skew deviation is a common symptom of cerebellar lesions. Moreover, unilateral damage to the utricular pathway due to involvement of the left nodulus might cause rightward conjugate ocular torsion and rightward head tilt.
