Acute disseminated encephalomyelitis in autoimmune hemolytic anemia.

A 16-year-old female with chronic autoimmune hemolytic anemia is presented. She was diagnosed with acute disseminated encephalomyelitis by clinical findings and magnetic resonance imaging (MRI), and the condition occurred after a systemic infection with Cryptococcus neoformans. Intravenous immunoglobulin therapy remarkably improved the patient's neurologic deficit and resolved abnormalities evidenced on MRI. To our knowledge, this report is the first of a pediatric patient with autoimmune hemolytic anemia complicated by acute disseminated encephalomyelitis that developed after an apparently successful treatment of cryptococcal meningitis.
