Hunt syndrome (RHS) is a clinical diagnosis characterized by otalgia, vesicular lesions of the auditory canal and auricle (herpes zoster oticus), and ipsilateral facial paralysis.1 It is associated with reactivation of the varicella zoster virus (VZV) in the geniculate ganglion.2 The risk is highest in the elderly, females, Caucasians, and those with a family history of shingles.3 RHS has an incidence of about 5 in 100,000 population in the US, and may be associated with up to 20% of cases of Bell’s palsy due to cranial nerve VII (lower motor neuron) dysfunction.4,5 The mainstay of RHS treatment includes oral antivirals (e.g. acyclovir); however, there is no strong evidence that it improves outcomes.4 RHS due to VZV reactivation has been associated with the development of vasculopathies that increase the risk for aneurysms, intracranial hemorrhage, and stroke.6 This highlights the importance of making the correct diagnosis in seemingly straightforward cases of unilateral cranial nerve VII palsy, as the diagnosis of RHS is an established risk factor for stroke and other serious outcomes associated with VZV vasculopathies.7
