Levator-sparing nuclear oculomotor palsy. Clinical and magnetic resonance imaging findings.
Two patients with diplopia presented with unilateral oculomotor palsy, defective elevation of the contralateral eye, and sparing of the levator palpebrae muscle. In each case, magnetic resonance imaging disclosed an infarction of the oculomotor nuclear complex in the mesencephalon. This clinical neuroradiological correlation is consistent with Warwick's scheme pertaining to the neuroanatomy of the oculomotor nuclear complex and demonstrates the utility of MRI in diagnosing ocular motility disorders of brainstem origin.
