原发性肺非霍奇金氏淋巴瘤的CT诊断

摘要

目的 分析原发性肺非霍奇金氏淋巴瘤的CT表现,提高对此病的认识.方法 回顾性分析经病理及免疫组织化学证实的肺非霍奇金氏淋巴瘤的CT及临床资料,运用诊断标准对确诊为原发性非霍奇金氏淋巴瘤的11例患者进行分析.结果 CT表现:双肺多发病变3例,单肺多发病变5例,单肺孤立病变3例.其中:肺内肿块型5例,肺炎型4例,既有肺内肿块又有斑片影的2例.8例行增强CT的均表现为轻度均匀强化,病灶内未见明显坏死液化区;伴有胸腔积液的有2例,胸膜增厚的2例.11例患者中有3例行开胸手术,术后病检为非霍奇金氏淋巴瘤;另外8例均行CT导向下穿刺活检行病理及免疫组织化学检测为非霍奇金氏淋巴瘤.结论 原发性肺非霍奇金氏淋巴瘤的影像学表现多样,其中以结节肿块型和肺炎实变型最常见,结节肿块周围出现磨玻璃影具有一定特征性.%Objective To study the CT manifestations of primary pulmonary non-Hodgkinp't lymphoma and to improve the rate of successful diagnosis of primary pulmonary non-Hodgkin't lymphoma. Methods The clinical data and CT images of 11 cases with primary pulmonary non-Hodgkin's lymphoma were retrospectively analyzed. All cases were comfirmed by histopathology and immunohistochemistry. Results The manifestations of the 11 cases were as follows:5 cases had multiple lesions of both lungs, 3 cases had multiple lesions of one lung and 3 cases had solitary lesion. 5 cases showed pulmonary mass or nodules; 4 cases showed consolidation and 2 cases had both masses and consolidation. 8 cases showed light well-distributed enhancement after contrast injection. 2 cases had pleural effussion and another 2 cases had pleural thickening. Conclusion The CT manifestations for primary pulmonary non-Hodgkin's lymphoma may be various and nonspecific. Pulmonary mass and consolidation with air bronchogram are common. A few features remain characteristic, such as masses acompanied with ground-glass opacity.
