Relapsing Polychondritis

Abstract

We present a 54-year-old woman with 3-month history of skin rash and bilateral hearing loss. Multiple investigations including biopsy failed to reveal the underlying diagnosis of relapsing polychondritis, until 18 F-FDG PET/CT demonstrated a characteristic FDG activity pattern-the otorhino-tracheobronchial triad. The patient was subsequently diagnosed to have relapsing polychondritis and received treatment. The second FDG PET/CT revealed a differential response in different disease sites, which prompted an escalation of treatment.
