摘要
目的探讨肺泡蛋白沉积症的多层螺旋CT(MSCT)表现及其诊断价值。方法回顾分析7例经肺泡灌洗或纤维支气管镜肺穿刺活检病理证实的肺泡蛋白沉积症病人的MSCT资料,分析肺部病变的形态、密度及分布情况。结果本组双肺弥漫性斑片状或磨玻璃样病变者7例,病灶与正常肺组织间分界清楚,呈地图样分布者5例。在磨玻璃影中可见弥漫性分布的网格状影,呈"铺路石征"者4例;在斑片状阴影者中见支气管充气征者4例。同一病例中可同时有上述几种改变。结论肺泡蛋白沉积症有特征性的MSCT表现,MSCT对肺泡蛋白沉积症定性诊断有重要价值。
Objective To investigate the manifestations of pulmonary alveolar proteinosis （PAP） on multislice CT （MSCT） and assess its diagnostic value of this disease. Methods A review of MSCT data of seven patients with PAP-confirmed by trans alveolar lavage or bronchoscopie lung needle biopsy was clone with regards to their form, density and distribution in the lung. Results Diffused plaque or ground-glass like lesion appearance was seen in all seven in this group, with a clear boundary between normal lung tissue and foci, five showed map-like distribution. Diffusedly lattice-like shadow could be seen in ground-glass picture, appearing as cobble-stone sign, in four patients. Air bronchogram was shown in patching shade in four. The above chan- ges could be found in one patient at the same time. Conclusion PAP has distinctive features on MSCT, which has an important value in the qualitative identification of this condition.
