[A case of Cryptococcus gattii pneumonia]

Cryptococcus gattii often causes meningitis, but rarely causes pulmonary infections. Here, we reported a patient with asymptomatic pulmonary cryptococcosis caused by Cryptococcus gattii. The patient presented to the thoracic surgery department with an isolated pulmonary nodule that had been present for three years and underwent a thoracoscopic pulmonary wedge resection. Postoperative pathology was consistent with Cryptococcus gattii infection. Although the incidence of Cryptococcus gattii infection is lower than that of Cryptococcus neoformans, the neurological involvement is common and has severe complications. In this report, the risk factors, symptoms, diagnosis, treatment, and prognosis of Cryptococcus gattii pneumonia were discussed to improve clinical awareness of this disease.
