Abstract:
Objective To evaluate the CT findings of invasive pulmonary aspergillosis(IPA) in patients with leukemia.Methods Plain CT scanning of chest was performed in 9 cases of leukemia in company with IPA proved by sputum culture.5 of them underwent over twice CT re-scanning,CT findings of IPA were analysed.Results The lesions were seen more common in the bilateral upper lobe and dorsal segment of lower lobe,mainly located in the peripheral and sub-pleural lung field.Of the 9 cases,the lesions appeared as multi-nodular shadows in 5,single nodule in 2 and sub-pleural consolidation with ground-glass opacity around them in 2,of these 2 cases,one accompanied by multi-nodules.Halo-sign around the nodules in 6 cases and air cresent sign or cavity in 6 were seen.There were scattered ground-glass opacities and patchy attenuations in the bilateral lung in 4 cases.The adjacent pleura of lesion was slightly thinkened in 5 cases.Conclusion The incidence of IPA in leukemia patients is rather high,and CT features of IPA are of certainly characteristics.
