目的研究免疫正常人群肺原发性隐球菌病的影像学表现。方法回顾性分析经组织病理学确诊的26例原发性肺隐球菌病的临床表现和CT征象。结果 26例中19例有临床表现,以咳嗽最多,共14例。CT最常见征象为结节,共21例,其中8例单发,9例簇状多发,4例散在多发;13例结节形态不规则,19例边界不清楚;21例结节阳性病例中14例有结节周围晕征。病灶多发生于双肺下叶(15例),并多分布于外带(18例)。磨玻璃样影多见于老年人群,占66.7%。结论免疫正常人群原发性肺隐球菌病胸部CT典型的表现为双肺下叶外带簇状多发结节灶并结节周围晕征。而在老年人群中发现磨玻璃样影,无论伴或不伴结节,均需高度考虑隐球菌病可能。
Objective To study the imaging manifestations of pulmonary cryptococcosis in immunized normal population. Methods The clinical manifestations and CT signs of 26 patients with primary pulmonary cryptococcosis diagnosed by histopathology were retrospectively analyzed. Results Of 26 cases, 19 cases had clinical manifestations, with the most cough, a total of 14 cases. CT most common signs of nodules, a total of 21 cases, of which 8 cases of single, multiple tufts in 9 cases, scattered in 4 cases; irregular nodules in 13 cases, 19 cases of border is not clear; 21 cases of nodular positive cases Fourteen cases had halo sign around nodules. Lesions occurred in the lower lobe of lung (15 cases), and more in the band (18 cases). Grinding glass-like more common in older people, accounting for 66.7%. Conclusions CT findings of chest CT in patients with primary pulmonary cryptococcosis in immunocompetent population are typically characterized by clusters of clusterlike multiple nodules in the lower lobe of lower lung and peripheral halo sign. Found in the elderly crowd ground glass-like shadow, either with or without nodules, are highly considered cryptococcal disease may be.
