目的：探讨肺内孤立结节型肺隐球菌病的多排螺旋CT表现，以提高其诊断正确率。方法回顾性分析18例经病理证实的孤立结节型肺隐球菌病患者的螺旋CT表现。结果18例病变中，有13例位于胸膜下，12例位于肺下叶；CT表现为类圆形结节16例、空气支气管征15例、血管集束征8例、宽基底与胸膜相连7例、晕征6例、胸膜反应5例、胸膜凹陷2例、毛刺征4例、分叶征2例。结论孤立结节型肺隐球菌病的多排螺旋CT表现有一定的特征性，认真分析其征象有助于提高该病的诊断正确率。%Objective To investigate the clinical manifestations of pulmonary crytococcosis (PC) of solitary nodular type as illustrated by multi-spiral computed tomography so as to improve the diagnostic accuracy.Methods The CT images of 18 patients diagnosed with pulmonary crytococcosis were reviewed retrospectively, all the diagnoses were pathologically conifrmed.Results Among the 18 cases, 13 nodules were located in subpleural regions and 12 nodules were located in lower lobes. CT images indicated that circular nodules were found in 16 cases, air bronchogram was found in 15 cases, vascular convergence was found in 8 cases, 7 cases clinged to pleura with wide basement, halo sign was found in 6 cases, pleural reaction was found in 5 cases, pleural indentation was found in 2 cases, spicule sign was found in 4 cases, slender spiculation was found in 2 cases.Conclusion As manifested by the multi-spiral computed tomography imaging, the clinical features of pulmonary cryptococcosis of solitary nodular type had certain characteristic idiosyncrasy. Careful analysis of CT imaging of the solitary PC can help improve the diagnostic accuracy.
