Pericardial tamponade presenting as abdominal pain in a patient with systemic lupus erythematosis.

Abdominal pain is a common complaint in children presenting to the emergency department. Patients with systemic lupus erythematosus (SLE) are at increased risk of infection, bowel necrosis and perforation, especially if they are taking nonsteroidal anti-inflammatory drugs, corticosteroids or immunosuppresive agents, which may mask the signs and symptoms of the underlying condition, hence delay diagnosis and treatment. This article presents the case of an adolescent girl whose abdominal pain was related to cardiac tamponade and provides an overview of the cardiac and gastrointestinal manifestations of SLE.
