(A) Normal chest x-ray at day +1 following allogeneic HCT; (B) S.maltophilia-related sepsis and ultimately fatal diffuse pulmonary hemorrhage at day +12 with detection of S.maltophilia in tracheal aspirates. (C, D) 17-years old male post allogeneic HCT for acute lymphoblastic leukemia (ALL) (patient 5). (C) Normal chest x-ray obtained during evaluation prior to transplantation; (D) S.maltophilia-related sepsis with ultimately fatal diffuse pulmonary hemorrhage on day +1 post-transplant. (E, F) 11-years old female with ALL (patient 3). First tracheal detection of S.maltophilia four days after microbiologically proven methicillin-susceptible Staphylococcus aureus pneumonia. (E) Middle lobe bleeding and atelectasis on chest CT-scans twenty-four days after first S.maltophilia detection. (F) Intrapulmonary abscess thirty-one days after first S.maltophilia detection; in the context of surgical resection, documentation of S.maltophilia from intraoperative tissue. Death forty-five days after first S.maltophilia detection.
