Allescheria (Petriellidium) boydii brain abscess in a child with leukemia

A 3-year-old boy with acute lymphoblastic leukemia developed a right frontal lobe abscess from which Allescheria (Petriellidium) boydii was cultured. The mycotic infection complicating his underlying disease appeared to be confined to the brain. Surgical drainage and therapy with amphotericin B were followed by eventual recovery with no neurologic deficits.
