侵袭性肺曲霉菌病的影像学诊断

目的 探讨侵袭性肺曲霉菌病（IPA）的X线及CT表现，提高对该病的认识。方法回顾性分析经病原学或病理组织学证实的IPA6例（男4例、女2例）。基础病变包括肾移植术后5例及白血病1例，全部病例均行胸部X线及CT检查。结果4例表现为多发斑片状及片状影，其中2例伴空洞形成，1例表现为多发小结节影，1例表现为单发团块状影。影像诊断肺霉菌病3例，误诊3例。结论IPA的影像学表现无特异性，影像学检查结合临床资料对本病的诊断有一定价值。

Imaging diagnosis of invasive pulmonary aspergillosis

]Objective To study the X-ray and CT findings of invasive pulmonary aspergillosis (IPA) and to elevate the recognition of this disease.Methods Imaging data of 6 patients with IPA which was confirmed by etiology or histopathology were retrospectively analyzed.The basic lesions of IPA were secondary to renal transplantation(n=5)and leukemia(n=1).All patients underwent chest X-ray plain film examinations and CT scans.Results On chest X-ray and CT images,intrapulmonary multiple mottling shadows and patchy shadows were found in 4 cases in whom 2 cases were complicated with cavity formation,intrapulmonary multiple nodular shadows and single mass shadow in 1 each.Based on imaging findings,3 cases were correctly diagnosed while other 3 cases were misdiagnosed.Conclusion Imaging findings of IPA are not specific but the integration of imaging and clinical data has important value to diagnose this disease.
