摘要
目的:探讨肺继发性淋巴瘤的CT表现特征,以提高诊断正确率。材料和方法:回顾性分析临床或病理证实的26例肺继发淋巴瘤的CT征象,其中15例为非霍奇金淋巴瘤(NHL),11例为霍奇金病(HD)。本研究采用GEHispeedCT/i,10例平扫,16例直接增强扫描。结果:CT表现多样:肺内毛玻璃样影(NHL13vsHD6);单发或多发肿块结节及肿块样实变(NHL10vsHD8),其中仅HD组肿块中有4例病灶密度不均匀,5例见毛玻璃样晕症;黍粒样结节(NHL1);支气管血管束增粗(NHL1vsHD1);肺门纵隔淋巴结肿大(NHL9vsHD8);胸膜侵犯(NHL5vsHD2);心包累及(NHL2vsHD1);常为多个征象合并出现(NHL12vsHD5)。可分为以下四个类型:肺炎肺泡型(NHL3vsHD1),肿块(结节)型(NHL2vsHD2),黍粒型(NHL1),混合型(NHL12vsHD5)。结论:多样性为肺继发性淋巴瘤的特点,不均匀的肿块或伴有病灶周围的毛玻璃样晕症多见于HD,对诊断可能有帮助。
Purpose： To discuss the CT features in secondary pulmonary lymphoma, to improve the diagnosis accuracy. Materials and Methods： We retrospectively analyzed 26 pulmonary lymphomas proved by clinical or pathology. There were 15 NHL cases and 11 HD patients. Non- enhanced CT scanning was performed with GE Hispeed/i in 10 cases, and enhanced CT scanning in 16 cases. Results： CT manifestations of NHL and HD consisted of ground- glass opacity （NHL 13 vs HD 6）;single or multiple nodules, mass and mass - like consolidation（NHL 10 vs HD 8） , 4 heterogeneous mass and 5 mass with a halo of ground- glass shadowing at lesion margins only in HD; miliary nodule（NHL 1）, peribronchovascular thickening（NHL 1 vs HD 1）, hilar and mediastinal adenopathy（NHL 9 vs HD 8）, pleural invasion（NHL 5 vs HD 2）, cardic（NHL 2 vs HD 1） involvement; multiple manifestations（NHL 12 vs HD 5） were usually shown both in NHL and HD. Lymphomatons involvement of lung demonstrated 4 patterns： Pneumonic - alveolar（NHL 3 vs HD 1） ,nodns or mass（NHL 2 vs HD 2） ,miliary nodules（NHL 1）, mixture pattern（NHL 12 vs HD 5） .Conclusion： Variety was the characteristic feature of secondary pulmonary lymphoma. Heterogeneous mass and halo of ground - glass shadowing at lesion margin maybe the main features of HD.
