摘  要:目的 回顾性分析支气管侵袭性肺曲菌病的高分辨率CT(HRCT)表现,探讨HRCT在该病诊断中的价值.方法 收集30例经纤维支气管镜活检、CT导引下穿刺活检或痰培养证实的支气管侵袭性肺曲菌病的临床资料及影像学资料,所有HRCT图像均经2位经验丰富的胸部影像学主任医师阅片并分析总结其征象.结果 30例患者,19例具有多种CT征象,其中树芽征8例,支气管狭窄6例,支气管扩张8例,磨玻璃样密度灶(GGO)8例,腺泡结节10例,结节灶12例,腺泡结节灶伴有晕征4例,结节灶伴有晕征9例,空洞10例.11例具有单一CT征象,树芽征2例,支气管扩张2例,GGO 1例,腺泡结节2例,结节灶伴有晕征2例,空洞2例.30例病例中各征象出现率为:树芽征33.3%,支气管狭窄20%,支气管扩张33.3%,磨玻璃影30%,腺泡结节40%,结节灶46.6%,晕征53.3%,空洞40%.结论 支气管侵袭性肺曲菌病HRCT的主要征象是树芽征、支气管管腔狭窄或扩张,肺内见磨玻璃影、腺泡结节、结节灶,空洞,结节及空洞周围有晕征.支气管扩张合并树芽征、腺泡结节及晕征对诊断本病具有较高的特异性.Objective To analyze retrospectively the HRCT signs in the patients with invasive pulmonary aspergillosis and evaluate the value of HRCT in the diagnosis of invasive pulmonary aspergillosis.Methods The cilinical and HRCT images of 30 cases with invasive pulmonary aspergillosis diagnosed by fiber bronchoscopy, CT guided biopsy or sputum culture were collected.HRCT images were analyzed and the HRCT signs were summarized by two experienced chest imaging radiologists.Results 19 patients had a variety of CT signs, the sign of tree in bud was seen in 8 cases, bronchial stenosis 6 cases, bronchiectasis 8 cases, ground-glass opacity 8 cases, acinic nodules 10 cases, nodular lesions 12 cases, acinar nodules with halo sign 4 cases, nodules with halo sign 9 cases, cavity 10 cases.11 cases only had a single CT sign, the sign of tree in bud was seen in 2 cases, bronchiectasis 2 cases, ground-glass opacity 1 case, acinar nodules 2 cases, nodules with halo sign 2 cases, cavity 2 cases.The occurrence rates of various signs in 30 cases were as follows, the sign of tree in bud was 33.3%, bronchial stenosis 20%, bronchiectasis 33.3%, ground-glass opacity 30%, acinar nodule 40%, nodular lesion 46.6%, halo sign 53.3%,cavity 40%.Conclusion The main HRCT signs in the patients with invasive pulmonary aspergillosis includes tree in bud, bronchial stenosis, bronchiectasis, ground-glass opacity, acinar nodules, nodal lesions,pulmonary cavity and halo sign.The signs of bronchiectasis with tree in bud sign, acinar nodule and halo sign in the HRCT images are highly specific in the diagnosis of invasive pulmonary aspergillosis.
