A Visual Clue: When Back Pain Isn’t Spondyloarthritis
A recent clinical image published in Arthritis & Rheumatology highlights the diagnostic challenge of distinguishing axial spondyloarthritis from congenital spinal abnormalities. The case involves a patient referred for suspected axial spondyloarthritis who was ultimately diagnosed with Klippel–Feil syndrome, a rare condition characterized by the fusion of cervical vertebrae. This visual report underscores the critical importance of thorough differential diagnosis in rheumatology, where overlapping symptoms of inflammatory back pain and restricted spinal mobility can lead to initial misclassification.
Why it might matter to you: For rheumatologists, this case reinforces the necessity of integrating detailed imaging review with clinical assessment to avoid misdiagnosis in complex presentations of back pain. It serves as a practical reminder that congenital skeletal disorders can mimic the phenotype of inflammatory arthritis, potentially affecting decisions regarding the initiation of advanced biologic therapies. Ensuring diagnostic accuracy in such scenarios is fundamental to optimizing patient outcomes and avoiding unnecessary long-term treatment.
