Giant cell arteritis presenting as oculomotor nerve palsy with pupillary dilatation

Abstract

Acute complete oculomotor palsy with headache is a classical presentation of an extrinsic compression most commonly due to a posterior communicating artery aneurysm. We present a patient with such a presentation but with histologically proven giant cell arteritis. This possibility should be considered especially in the elderly to avoid complications and the need for angiography.
