摘要
目的分析HIV阴性肺隐球菌病的CT表现,提高对本病的认识及诊断水平。资料与方法回顾性分析2000-04～2011-10经病理或临床证实的20例HIV阴性肺隐球菌患者(包括7例免疫功能抑制者)的CT图像及临床资料。结果①肿块或结节型8例,其中孤立病灶3例,多发病灶5例,下肺、外周分布为主。②实变型7例,其中局限病灶3例,密度较高,边界较清;多发病灶4例,双肺散在分布。③混合型5例,表现为结节、团块、实变及磨玻璃影混合存在。20例患者中,晕征6例(30%),空洞11例(55%),支气管气相为10例(50%)。结论肺隐球菌病CT表现多样,病灶以下肺及外周分布为主,晕征、空洞及支气管气相有一定提示意义,有助于作出早期诊断,减少误诊。
Purpose To analyze the CT findings of pulmonary cryptococcosis （PC） in HIV-negative patients for a better understanding and diagnosis of the disease.Materials and Methods CT images and clinical records of 20 patients with histological or clinical confirmed PC were retrospectively reviewed. They were HIV- negative but 7 were immunocompromised. Results Eight presented as nodules or masses, 3 were solitary and 5 were multiple, located in the inferior and peripheral lung. Seven presented as consolidations, 3 were focal and high attenuation with clear border, 4 were multiple and scattered in the bilateral lungs. Five were mixed, showing nodule, mass consolidation of ground glass attenuation. The features of halo sign, cavitations and air bronchus sign were observed in 6 （30%）, 11 （55%） and 10 （50%） patients respectively. Conclusion CT findings of pulmonary cryptococcosis are variable, including inferior and peripheral lung distribution, halo sign, cavitations, air bronchus sign. These findings may be helpful for the diagnosis.
