Pericardial Effusion as the Initial Presentation of Systemic Lupus Erythematosus in a 37-Year-Old Female

Systemic lupus erythematosus (SLE) is a complex autoimmune disease that can affect various organs and systems in the body, leading to a wide range of clinical manifestations. Pericardial effusion, which is an accumulation of excessive fluid in the pericardial sac surrounding the heart, can be one of the early presentations of SLE in some individuals. When it occurs in young females, it can be particularly concerning, as SLE predominantly affects women of childbearing age. In this case report, we describe pericardial effusion as the initial presentation of SLE in a 37-year-old mother of four children. Importantly, early diagnosis and consistent follow-up are critical for improving the prognosis and quality of life for individuals with SLE.
