Anosmia in an adolescent: what to suspect?

Abstract

Anosmia is an uncommon complaint in children and adolescents and it is usually acquired. Congenital anosmia is usually associated with Kallmann’s Syndrome, but, rarely, can present with olfactory bulb agenesis as an isolated finding. We present a case of a 15-year-old boy with olfactory bulb agenesis without other structural abnormalities and hormonal deficiencies in whom the diagnosis of isolated congenital anosmia was made. We also briefly review the possible causes of anosmia, the recommended diagnostic workup, and management.
