Oculomotor Palsy from Neurocysticercosis Involving the Midbrain

ABSTRACT

Papilledema, pupillary abnormalities, and nystagmus are common neuro-ophthalmologic signs in neurocysticercosis (NCC). Oculomotor palsy rarely occurs and usually accompanies compression of the midbrain by supratentorial or subarachonoid lesions with or without inflammation and hydrocephalus. Oculomotor palsy from NCC involving the midbrain parenchyme has rarely been described. We report on a patient who presented with oculomotor palsy caused by mesencephalic NCC. The patient showed recurrences of symptoms in association with steroid tapering.
