Rapidly fatal acute bacterial myocarditis in a nonneutropenic child with acute lymphoblastic leukemia in remission

Abstract

The authors report a fatal case of acute bacterial myocarditis in a nonneutropenic child with acute lymphoblastic leukemia. She was admitted to the hospital with a urinary tract infection resulting from and remained persistently febrile despite resolution of the infection. On hospital day 4 signs of acute cardiac failure developed. Despite aggressive resuscitation measures, she died. Pathologic examination revealed the cause of death to be bacterial myocarditis. In addition, she was found to have a generalized decrease in her serum immunoglobulin levels. Acute bacterial myocarditis in patients with malignancy has been rarely reported. The rapid clinical deterioration and death in the patient in this report is particularly interesting.
