Anti‐ U1 ‐ RNP ‐Positive Inflammatory Myopathy Presenting With Dysphagia: A Case Report

Year: 2026

Type: article

Abstract: High-titer anti-U1-RNP antibodies may present with myopathy without fulfilling MCTD criteria. We report a 38-year-old woman with proximal weakness, elevated muscle enzymes, anti-U1-RNP positivity, and inflammatory myopathy on EMG/MRI, but lacking classic overlap features. Early recognition enabled immunosuppressive treatment and prevention of aspiration-related complications.
