[Diagnostic value of computed tomography in invasive pulmonary fungal infections].

OBJECTIVE

To analyze the computed tomographic (CT) features of invasive pulmonary fungal infections (IPFI) and evaluate the value of CT-guided percutaneous biopsy.

METHODS

Seventeen IPFI cases diagnosed by CT-guided percutaneous biopsy were recruited. The distribution, extent, density and size of IPFI were analyzed in correlation with the final diagnosis retrospectively. And the relationship with the causative factor of mycosis was also assessed.

RESULTS

(1) Candida albicans (n = 7) and cryptococcosis & aspergillus (n = 5) were identified. (2) It showed segmental on lobar consolidation within lung field (n = 6), mixture of patterns and nodule (n = 4) and mass (n = 7). (3) The overall diagnostic accuracy of fiberoptic bronchoscopy examination was 35.3%. (4) The incidence of complicated pneumothorax was 11.8% (2/17). These cases were self-limited without any special treatment.

CONCLUSION

The CT findings of PFI are too complex to be easily distinguished from other diseases. And the CT-guided percutaneous is a safe and effective procedure.
