Introduction: Rheumatoid Arthritis (RA) is a chronic inflammatory disease depicted by peripheral bone erosive damage leading to joint destruction, deformity and functional impairment. Shoulder involvement is less frequent than hands, wrists and feet, and relevant joint damage may be underdiagnosed if a lower threshold for careful analysis of this joint is not settled, especially in uncontrolled disease.
Case report: A 70-year-old male with a difficult-to-manage RA since 2010, presenting severe shoulder arthritis with MRI showing a striking giant geode in the left humeral head.
Conclusion: An impressive MRI image showing a giant geode in poorly controlled RA should alert rheumatologists to raise suspicion of shoulder involvement for early investigation and treatment.
