目的探讨隐球菌感染肺结节患者的多层螺旋CT扫描临床表现。方法分析过去五年间19例经手术切除病理或者体外穿刺活检证实属于隐球菌感染肺结节的患者,分析其临床特点、肺部影像学特征、组织病理学改变及治疗转归。所有研究对象均进行多层螺旋CT扫描,其中进行增强扫描者为9例。所有患者随访超过半年。结果其中CT临床表现为浸润实变型的为4例,网织结节或小结节型的为3例,肿块或结节型的为9例,混合型的有3例。19例研究对象均未见胸腔积液。7例见增粗的肺血管深入病灶内,有7例出现晕征。结论螺旋CT对肺隐球菌具有较好的辅助作用,但最终确诊还需要病原学检查。
Objective To investigate the clinical manifestations of multi-slice spiral CT in patients with cryptococcal pulmonary nodules. Methods Nineteen patients who underwent pathological resection or biopsy in vitro confirmed pulmonary cryptococcosis were analyzed in the past five years. The clinical features, pulmonary imaging features, histopathological changes and treatment outcome were analyzed. All subjects underwent multi-slice spiral CT scan, among which 9 patients underwent enhanced scan. All patients were followed for more than six months. Results CT clinical manifestations of invasive consolidation in 4 cases, reticular nodules or nodules in 3 cases, mass or nodular in 9 cases, mixed-type in 3 cases. None of the 19 subjects had pleural effusion. 7 cases see the thickening of the pulmonary vascular lesions, there are 7 cases of halo sign. Conclusion Spiral CT has a good auxiliary effect on pulmonary cryptococcosis, but the final diagnosis also requires etiological examination.
