CT在原发性肺隐球菌病诊断中的应用价值

Imaging diagnosis value of CT in primary pulmonary crytococcosis

目的探讨多层螺旋CT对原发性肺隐球菌病(Primary pulmonary crytococcosis,PPC)的应用价值。方法回顾性分析我院18例经病理证实的PPC的临床及CT影像学资料,分析病变的数目、大小、形态、密度、边界、强化方式。结果 PPC主要表现为发热、咳嗽或胸痛,症状一般较轻。PPC病灶以多发结节影8例(44.4%)最多见,其次为孤立不规则团块影5例(27.8%),单发结节2例(11.1%)、实变影2例(11.1%)及混合性结节影1例(5.6%)较少见。结论 PPC在CT表现上具有一定特征性,结合临床,有望作出准确诊断。

Objective To explore CT imaging findings and clinical application value in primary pulmonary crytococcosis（PPC）. Methods Clinical data and CT findings in 18 patients with PPC confirmed by operation and pathologic examination were retrospectively analysed. The size, shape, density, boundary and strengthen of the mass were observed.Results The clinical symptoms of PPC characterized by mind fever, cough or thoracalgia. The CT appearances of PPC were various, including multiple pulmonary nodules in eight cases（44.4%）, isolated irregular mass in five cases（27.8%）,solitary nodule in two cases（11.1%）, lobar consolidation in two cases（11.1%） and mixed nodules in one case（5.6%）.Conclusion PPC has certain characteristic on CT, combining with clinical information, the preoperative diagnosis and differential diagnosis can be made more predicatively.
