目的　加深对各种肺真菌病的临床影像学认识 ,提高影像学诊断水平。资料与方法　对 34例经手术、痰检、脑脊液培养证实的肺真菌病的临床影像学资料进行随访和回顾性分析。结果　影像学表现有 :团块状球形病灶共 1 9例 (其中 6例有“新月征” ,4例有“空气支气管征” ,3例边缘有“毛刺征” ,2例有“晕征”)。两肺或一肺斑点状小结节状病灶共 1 1例。大的肺脓肿改变 1例。大片状实变 1例。纵隔淋巴结增大伴胸腔或心包积液 1例。结论　本病临床症状无特征性 ,病史有参考价值。在影像表现上球形病灶有新月征、空气支气管征、晕征对本病有提示价值 ,如发现半月形空洞内有随体位改变的“洞中球征” ,对肺曲菌病有重要诊断价值。本病的确诊需病理和细菌学检查 Objective To deepen the clinical imaging knowledge of various pulmonary mycosis and improve the diagnostic level of imaging. Materials and Methods Clinical imaging data of 34 cases of pulmonary fungal diseases confirmed by operation, sputum examination and cerebrospinal fluid culture were followed up and retrospectively analyzed. Results The imaging findings were as follows: lumpy globular lesions were found in 19 cases (6 cases had “crescent” sign, 4 cases had “bronchial air sign”, 3 cases had “burr sign” at the edge and 2 cases had “halo sign ”). A total of 11 cases of small nodular lesions of either lung or lung were spotted. Large lung abscess changes in 1 case. A large piece of real change in 1 case. One case of mediastinal lymph node enlargement with thoracic or pericardial effusion. Conclusion The clinical symptoms of this disease without characteristic, history has a reference value. Spherical lesions in the imaging manifestations of crescent sign, air bronchogram, halo sign of the disease prompted value, such as found in the lunate cavity with the position change “hole ball sign”, an important diagnosis of pulmonary aspergillosis value. The diagnosis of this disease requires pathological and bacteriological examination
