Case of cytomegalovirus pneumonia presented as pneumothorax in 4-month-old healthy infant

Abstract

Cytomegalovirus (CMV) is the most common agent of congenital infections and opportunistic infections in an immunocompro mised host. CMV in an immunocompetent host has inapparent infections, which are usually asymptomatic or cause mild mononu cleosis-like symptoms. However, severe CMV diseases, such as pneumonia, hepatitis, gastrointestinal disease, often occur in a healthy infant. The association of CMV pneumonia with the development of pneumothorax has rarely been reported. We experi enced a case of CMV pneumonia presenting as pneumothorax in a 4-month-old healthy infant, who was successfully treated with supportive care. CMV was confirmed by using CMV polymerase chain reaction of tracheal aspirates. This case suggested that CMV should be considered as a cause of viral pneumonia during the infant period.
