<jats:title>Abstract</jats:title> <jats:sec> <jats:title>Objective</jats:title> <jats:p>To evaluate 18F-fluorodeoxyglucose (FDG) PET/CT in the assessment of disease activity, extent of the disease and response to therapy in relapsing polychondritis.</jats:p> </jats:sec> <jats:sec> <jats:title>Methods</jats:title> <jats:p>Twenty-five patients (9 men, 16 women) with a mean age of 38.2 years (s.d. 13.7; range 18–62), diagnosed to have relapsing polychondritis according to Damiani and Levine’s modification of McAdam’s criteria, who underwent PET/CT examination were included. Ten patients underwent a second PET/CT examination after therapy or during follow-up. Clinical symptoms and auxiliary examination findings were recorded. PET/CT findings were reviewed and correlated with the clinical symptoms.</jats:p> </jats:sec> <jats:sec> <jats:title>Results</jats:title> <jats:p>The major symptoms were aural pain (n = 21), nasal pain (n = 10), stridor (n = 5), cough (n = 9), fever (n = 8) and laryngeal tenderness (n = 8). The initial PET/CT was positive in 23/25 patients. PET/CT revealed involvement of auricular (n = 14), nasal (n = 8), laryngeal (n = 7), tracheobronchial (n = 6) and Eustachian (n = 3) cartilages with a mean maximum standardized uptake value (SUVmax) of 4.1 (s.d. 2.5; range 1.7–12.7). Fair correlation of aural/nasal pain/stridor with FDG avidity of cartilage involvement on PET/CT was noted. The key finding was detection of asymptomatic large airway involvement in seven patients (28%). Re-examination PET in 10 patients revealed complete therapeutic response (n = 5), partial response (n = 1), stable disease (n = 1), progressive disease (n = 1) and disease recurrence (n = 2).</jats:p> </jats:sec> <jats:sec> <jats:title>Conclusion</jats:title> <jats:p>FDG PET/CT is a useful tool for the assessment of the disease activity and extent. It identified activity in clinically inaccessible sites that are of clinical significance. It is also useful in assessing treatment response and finding relapse.</jats:p> </jats:sec>
