A 73-year-old woman with arthritis treated with immunosuppressive drugs and a lung infection developed a life-threatening narrowing of her airway caused by a rare fungal infection called Scedosporium apiospermum. Doctors used a combination of emergency measures including a breathing support machine, insertion of a special tube to keep the airway open, and strong antifungal medication to treat the infection. After six months of treatment, the fungal infection was completely gone and the special airway tube was successfully removed, allowing normal healing.
