Abstract: The X-ray computed tomography (CT) appearance of 4 cases with pulmonary cryptococcosis (PC) diagnosed by pathological examination in our hospital was retrospectively analyzed. The appearances of PC on CT were various: solitary lesion in 1 case, multiple lesions in single lobe in 2, and multiple lesions in multiple lobes in 1. There were total 52 lesions in 4 cases; the diameter of nodules or masses was 3 - 75 mm. Cavitations were found in 1 case; lesions appeared obviously enhanced and one lesion showed central necrosis. Two cases underwent pulmonary lobectomy; and 2 cases received core cutting needle biopsies, after antifungal therapy for 3 months to 1 year the lesions showed being absorbed. In summary, the CT appearance of PC is non-specific with various modes and forms. PC should be considered when multiple nodules or masses scattered in subpleural zone, accompanied with ground-glass opacity and obviously enhanced. The examination of pathogen and pathology at the beginning is crucial for improving diagnostic accuracy.
