The imaging diagnosis of pulmonary aspergillosis

Objective: To discuss the imaging characteristics of pulmonary aspergillosis for the clinical diagnosis of this disease. Methods: 9 cases of pulmonary aspergillosis in our hospital for about 10 years were retrospectively reviewed. All the cases were confirmed by operation, pathology and bacteriology. The chest X-ray films, the routine and contrast-enhanced CT scanning (with 5mm slice thickness and 5mm spacing) were analyzed. Results: Among all the 9 cases, 5 of them located in right lung, 3 of them located in left lung, 1 of them located in both lung simultaneously. The lesions represented as single or multi nodules with crescent sign, ball in cavity sign, halo sign or air bronchogram The ground-glass opacities or patched low density opacities were seen in some cases. Conclusion: Pulmonary aspergillosis have some characteristic imaging signs. Combined with laboratory and other pathological examination, it can be diagnosed correctly and thus an early treatment can be obtained. (authors)
