Sepsis and subsequent organ dysfunction are significant complications in patients with acute lymphoblastic leukemia. This case report details the successful use of combined inhaled and intravenous colistin in a 22-year-old male with high-risk acute lymphoblastic leukemia who developed tumor lysis syndrome, febrile neutropenia, respiratory failure, sepsis, septic shock, capillary leak, and prolonged mechanical ventilation requiring tracheostomy. Colistin inhalation, administered via a vibrating mesh nebulizer, was well-tolerated and led to clinical improvement. This report contributes to the growing evidence supporting the adjunctive use of inhaled colistin in multidrug-resistant infections, particularly in immunocompromised patients.
