A young man with cerebral palsy developed a rare lung infection caused by Magnusiomyces capitatus, a fungus that usually only affects people with weakened immune systems. Doctors diagnosed the infection by analyzing fluid from his lungs and identified the fungus using advanced laboratory techniques. The patient improved after being treated with an antifungal medication called voriconazole. This case highlights that this rare fungal infection can occur in otherwise healthy people, especially those with conditions affecting their ability to clear lung secretions.
