Horner Syndrome in Giant Cell Arteritis: Case Series and Review of the Literature

Conclusions: This case series describes 2 patients with new diagnosis of GCA and concurrent Horner syndrome, with new diagnosis of likely nuclear/fascicular fourth nerve palsy in one patient and skew deviation in the other. In both patients, vasculitis presumptively affected vertebral arteries and their branches supplying the first-order sympathetic neurons in the brainstem. Considering the severe complication of permanent vision loss in GCA, this diagnosis should be considered in older patients presenting with concurrent new onset of Horner syndrome.
