Isolated abducens nerve palsy following upper respiratory infection in a patient with ipsilateral chronic sphenoid sinusitis.

ABSTRACT: The abducens nerve, which is vulnerable because of its complex anatomy at the skull base, is seldom affected by acute or severe sphenoid sinusitis. Notably, abducens nerve palsy following asymptomatic chronic rhinosinusitis (CRS) in a healthy young individual after a mild upper respiratory infection (URI) remains undocumented in the literature. Herein, we report a case of acute unilateral abducens neuropathy in a healthy 35-year-old woman with CRS in the ipsilateral sphenoid sinus, following a mild URI 2 weeks earlier. She presented with sudden-onset diplopia, was afebrile, and had normal serum inflammatory biomarkers.
