Implication

Case report highlights misdiagnosis of oligoarticular juvenile idiopathic arthritis presenting as monoarthritis in a child, suggesting the need for advanced imaging.

Key Points

  • To discuss a rare presentation of oligoarticular juvenile idiopathic arthritis involving the PIP joint.
  • Case report of an 8-year-old girl with isolated PIP joint swelling and stiffness.
  • Evaluation included imaging and biopsy, followed by MRI and synovial fluid analysis.
  • Investigated persistent monoarthritis symptoms.
  • Initial evaluations suggested trauma due to swelling in the PIP joint.
  • MRI and synovial fluid analysis revealed an inflammatory process related to JIA.
  • Isolated involvement of small joints like the PIP joint is uncommon and can complicate diagnosis.
