摘要
目的分析肺硬化性血管瘤（pulmonary sclerosing hemangioma，PSH）薄层CT征象及其诊断价值。方法回顾14例病理证实PSH临床和薄层CT资料，分析病变一般CT征象（部位、形态、大小、密度，以及强化程度和方式、淋巴结肿大）和相对特殊征象（钙化、囊变、空气新月征、贴边血管征、尾征、肺动脉为主征、晕征等）。结果①病变位于左上肺2例，左下肺3例；右上肺3例，右中肺2例，右下肺4例。②14例病变均为单发病灶；病灶边缘无毛刺征；大小不一；其中9例为类圆形，5例为不规则形。③平扫密度均匀9例，不均匀5例。14例均表现为中度或明显强化，其中8例均匀强化，6例不均匀强化。④1例合并纵隔淋巴结肿大；2例出现点状及小斑片状钙化，其中1例为薄层CT图像检出；囊变2例；贴边血管征3例；尾征2例。结论PSH好发于中青年女性，当病变表现相对特殊CT征象时可以定性诊断，薄层CT重建可提高病变诊断准确率。
Objective To investigate the thin slice computed tomography（CT） features and the value of diagnosis for pulmonary sclerosing hemangioma（PSH）. Methods The thin slice CT data of fourteen cases confirmed by histopathology were retrospectively reviewed including common features（ sites, morphologic features, size, density, the degree and pattern of contrast enhancement, lymphadenopathy） and relatively distinctive features （ calcification, cystic - like area, airtrapping zone, vessels at its periphery, tail sign, prominent pulmonary artery sign, halo sign and so on）. Results Among the fourteen patients, ten of the patients were female and four were male with a median age of 45.9 （range from 18 to 68）. 1 ）Two PSH located in the left upper lobe,three in the left lower lobe;three in the right upper lobe, two in right middle lobe and four in the right lower lobe;2）All fourteen lesions were solitary and did not share the feature of speculation, nine of which presented as subrotund lesions and the rest five were irregular;3 ）The density of the lesions on plain CT was homogeneous in nine and heterogeneous in five. Eight cases presented as homogeneous enhancement whereas the rest six had heterogeneous enhancement ;4）Mediastinal lymphadenopathy was presented in only one patient ;5 ）Two PSH had calcification, one of which was detected in thin slice CT images. Cystic -like area was found in two cases, vessels at its periphery was found in three and tail sign in two. Conclusion PSH more commonly occurs in middle - aged female. If there presents distinctive features on thin CT scans, the qualitative diagnosis can be made. So thin slice CT images can increase the accuracy of diagnosis.
