P50 Difficult to Diagnose SLE Manifestations Associated with Cardiac Arrest, Myocarditis, Chronic Pericarditis, Polyneuropathy

A 44-year-old female patient with systemic lupus erythematosus (SLE) presented with general weakness, dizziness, significant weight loss, subfebrility, fatigue, hair loss, and joint pain. She experienced cardiac arrest during examination and was successfully resuscitated. Diagnosed with myocarditis, chronic pericarditis, and critical illness polyneuropathy, she received extensive cardiac treatment, including mechanical circulatory support and tetracycline therapy. Following immunological treatment with solumedrol and IVIG, she began recovering from neuromuscular symptoms. The patient met several SLICC criteria for SLE and has been in remission for 2 years with maintenance therapy. This case highlighted the importance of extensive diagnostics in accurately diagnosing SLE-mimicking symptoms.
