Objective  To explore the diagnosis value of the low dose multi-slice spiral computed tomography (MSCT) imaging in pulmonary fungal infection in order to improve its diagnosis level. Methods  CT manifestations of 106 cases of pulmonary fungal infection confirmed by operation, pathology, mycetes cultivation and follow-ups of clinical therapy were retrospectively analyzed. All cases underwent low dose MSCT examinations including CARE dose 4D and sinogram affirmed iterative reconstruction technology, and 6 cases underwent contrast-enhanced CT scanning. Results  Among the basic MSCT findings of pulmonary fungal infection, they showed patch-nodular type in 54 cases, solid variant in 38 cases, and tumor type in 14 cases. In all cases, 91 cases displayed as mulifocality, 83 cases as polymorphism and 78 cases as polytropy. Among the 106 cases with comparative distinctive MSCT manifestations, bud of branch sign were showed in 39 cases, halo sign in 32 cases, wedge shape consolidation in 19 cases, ice needle sign in 15 cases, crescentic sign in 11 cases, air ring sign in 6 cases, and contra-halo sign in 4 cases. The nodules in the cavities were not enhanced in enhanced scan in 5 cases. Conclusions  There are some distinctive MSCT findings in patients with pulmonary fungal infection. Pulmonary fungal infection can be diagnosed with typical MSCT findings in close combination with the clinical information.
