Symptomatic perineural extension of fungal sinusitis in an immunocompetent person: imaging features.

Abstract

Perineural spread is a rare mode of spread for fungal infection, even more so in immunocompetent individuals. We report a 21-year-old immunocompetent man in which symptomatic perineural extension of aspergillosis along the maxillary division of trigeminal nerve was accurately diagnosed on imaging.
