Pulmonary hemorrhage associated with systemic lupus erythematosus in children

Abstract

Four children with systemic lupus erythematosus (SLE) and pulmonary hemorrhage are discussed. Radiologists should be aware of the possibility of such bleeding when confronted with diffuse parenchymal abnormalities in a child, particularly if there is (a) evidence of unexplained blood loss or (b) signs and symptoms of collagen vascular disease. Pulmonary hemorrhage may occur long before SLE is suspected and appear identical to idiopathic pulmonary hemosiderosis.
