Constrictive pericarditis in systemic lupus erythematosus. demonstration of immunoglobulins in the pericardium

A 17-year-old male with systemic lupus erythematosus presented with clinical signs of severe constrictive pericarditis that was confirmed by cardiac catheterization. At surgery, a fibrous pericardium was removed, followed by complete relief of symptoms. Immunopathology of the pericardial tissue revealed deposition of IgG, IgM, and C3. A review of the literature produced only three similar cases. Although rare, constrictive pericarditis, a potentially life threatening complication, may occur in systemic lupus erythematosus presumably with an immunological basis.
