Bilateral third nerve palsy and temporal arteritis.

BACKGROUND: Bilateral oculomotor palsy is a rare manifestation of temporal arteritis, and to our knowledge only 1 case has been described in the literature. OBJECTIVE: To investigate a possible case of temporal arteritis in a patient with bilateral third nerve palsy. DESIGN: Case report and review. SETTING: University hospital. PATIENT: A 65-year-old man had subacute pupil-sparing bilateral third nerve palsy. RESULTS: Temporal artery biopsy findings and response to corticosteroids are consistent with temporal arteritis. CONCLUSION: Temporal arteritis is a rare cause of ophthalmoplegia in elderly persons and may be unrecognized.

Isolated relative afferent pupillary defect secondary to contralateral midbrain compression.

BACKGROUND: Relative afferent pupillary defects are typically related to ipsilateral lesions within the anterior visual pathways. OBJECTIVE: To describe a patient who had a workup for headache and was found to have an isolated left relative afferent pupillary defect without any other neurological findings. DESIGN: We review the neuroanatomy of the pupillary light reflex pathway and emphasize the nasotemporal bias of decussating fiber projections, which accounts for the relative afferent pupillary defect contralateral to the described lesion. Result Magnetic resonance imaging of the brain revealed a pineal tumor compressing the right rostral midbrain. CONCLUSION: While rare, a relative afferent pupillary defect can occasionally occur secondary to lesions in the postchiasmal pathways. In these circumstances, the pupillary defect will be observed to be contralateral to the side of the lesion.
