RESUMEN
Bronchiolitis obliterans, a late, non-infectious pulmonary complication of bone marrow transplantation (BMT), is an obstructive airway disease associated with chronic graft-versus-host disease (cGVHD). We report a rare case of air-leakage syndrome including pneumothoraces, pneumomediastinum, and subcutaneous emphysema with bronchiolitis obliterans after allogeneic peripheral blood stem cell transplantation (PBSCT) from an unrelated donor. The pathogenesis of air-leakage syndrome is not fully understood, and its management has not yet been established. This patient was treated with high-concentration oxygen, tube thoracostomy, percutaneous drainage with a pigtail catheter to relieve the tension pneumomediastinum, and mechanical ventilatory support. The patient has now recovered and is being followed on an outpatient basis.
