Weakness, seizures, and encephalopathy have a broad differential diagnosis in patients with systemic lupus erythematosus (SLE). We present a case of a 26-year-old female with a recent diagnosis of SLE who experienced a clinical deterioration with quadriparesis, seizures, and encephalopathy. Her quadriparesis was found to be secondary to biopsy-proven hydroxychloroquine-induced myopathy with concomitant inflammatory myopathy. Her seizures and encephalopathy were suspected to be multifactorial in the setting of sepsis and critical illness with possible contributions from neuropsychiatric manifestations of SLE and macrophage activation syndrome. She experienced a dramatic clinical recovery with discontinuation of hydroxychloroquine, treatment of lupus disease activity with mycophenolate mofetil and prednisone, and antibiotic treatment for methicillin-sensitive Staphylococcus aureus (MSSA) bacteremia. This case-based review provides a systematic approach to quadriparesis, seizures, and encephalopathy in patients with SLE and an evidence-based discussion of antimalarial myopathy, which is of critical importance given the widespread use of antimalarial medications for rheumatologic diseases.
