Can giant cell arteritis present with a partial cranial neuropathy?

Giant cell arteritis (although giant cells on temporal artery biopsy are not a sine qua non) most typically presents to the neuro-ophthalmologist with ischemic optic neuropathy (usually anterior and sometimes posterior).

Ophthalmoplegia is uncommon in GCA but has been attributed to oculomotor and abd...

Yes. Although we most commonly think of giant cell arteritis (GCA) when an elderly patient presents with headache and vision loss from an ischemic optic neuropathy (AION or PION) or central retinal artery occlusion (CRAO), other cranial nerves can be affected as well. Ischemic third, fourth and sixt...

Admittedly, the yield is low. However, it is really important to have a...
