Core Tip

Core Tip: Relapsing polychondritis (RP) is a rare inflammatory disease involving the systemic cartilage. Its diagnostic criteria and clinical manifestations are well established; however, no previous studies have reported the involvement of the eustachian tube (ET) in RP. A 72-year-old Japanese woman with a history of redness of the auricles for 3 d was diagnosed with RP with pathological evidence. The magnetic resonance imaging (MRI) showed edematous ETs with contrast enhancement. The MRI manifestation was considered as inflammatory changes of the ET cartilage.
