    Summary

    Radiographs in rheumatoid arthritis (RA) can be misleading, with atypical findings mimicking other conditions. This study highlights five cases where RA radiographs suggested alternative diagnoses, emphasizing diagnostic challenges.

    Area of Science:

    • Rheumatology
    • Radiology
    • Diagnostic Imaging

    Background:

    • Rheumatoid arthritis (RA) diagnosis relies on clinical and radiographic evidence.
    • Radiographic findings in RA can occasionally present atypically.
    • Differential diagnosis is crucial for accurate patient management.

    Observation:

    • Seven out of 69 patients (10%) with confirmed rheumatoid arthritis exhibited atypical radiographic features.
    • These atypical features prompted consideration of alternative diagnoses, including gout, lupus erythematosis, and thrombophlebitis.
    • Five illustrative cases are presented in detail.

    Findings:

    • Atypical radiographic presentations in RA can obscure the correct diagnosis.
    • Misinterpretation can lead to delayed or incorrect treatment initiation.
    • Careful clinical correlation is essential when radiographic findings are unusual.

    Implications:

    • Clinicians must maintain a high index of suspicion for RA even with atypical radiographic findings.
    • Radiographic interpretation in RA requires consideration of a broad differential diagnosis.
    • Improved awareness of atypical RA radiographic patterns can enhance diagnostic accuracy and patient outcomes.
