Etanercept (ETN) can induce remission in many patients with rheumatoid arthritis (RA); however, successful
cessation is considered difficult. We present two cases with RA treated with ETN and successfully discontinued
ETN. Before ETN cessation, we evaluated the presence of synovitis using Magnetic Resonance Imaging (MRI) and
ultrasonography (US). Neither patient showed signs of synovitis in these examinations. MRI and US may provide
useful indicators in the clinical recommendations for ETN cessation in RA
