继发性肺淋巴瘤43例CT分析

目的探讨继发性肺淋巴瘤(SPL)的CT表现。方法回顾性分析经穿刺活检、手术病理证实诊断为SPL的43例患者的临床和CT资料。结果 43例病理类型中31例非霍奇金淋巴瘤(NHL),12例霍奇金淋巴瘤(HL);胸部CT示肺内结节影8例,其中多发实性结节影4例,单发实性结节影2例,多发浅淡磨玻璃样结节1例;大片实变19例,单发实变9例,其余10例均为多发片状实变影;团块影16例,单发团块4例,多发团块影12例,其中2例伴不规则空洞性团块。43例中7例接受增强检查,大部病灶呈不均匀轻中度强化,3例病灶内见坏死无强化区,1例伴不规则空洞,1例病灶内可见穿行血管。伴随其它CT表现包括10例伴有单侧胸腔大量积液,3例伴有单侧少量积液,1例伴有肋骨破坏及胸壁肿块影,7例纵隔、腋下淋巴结肿大,4例病例发现肺以外器官的侵犯。结论 SPL可表现为结节影、实变影及团块影,可单发、多发,掌握其CT影像特点,能够为临床诊疗提供帮助。

CT Analysis of 43 Cases of Secondary Pulmonary Lymphoma

Objective To investigate the CT features of sencondary pumlmonary lympuoma(SPL). Methods The clinical data and CT findings of 43 cases of SPL were retrospectively analyzed. All cases were diagnosed via lung biopsy or surgicao biopsy.Results Of the 43 cases with SPL, there were non-Hodgkin lymphoma(31 cases) and Hodgkin lymphoma(12 cases). The CT findings were classified into 3 types: nodular(8 cases), multiple nodular(4 cases), single nodular(2 case), groud glass opacity like nodules(2 cases). consolidation(19 cases), single consolidation(9 cases), with whole leaf consolidation(2 cases), multiple consolidation(10 cases). Lesions(16 cases), single lesion(9 cases), multiple lesions(7 cases), with cavity(2 cases). Of the 43 cases, 7 cases received enhanced examination, the major lesions were inhomogeneous and mild to moderate enhancement, 3 cases showed necrosis and no strengthening area, 1 case were irregular cavity, and 1 cases showed penetrating vessels. Other CT manifestations included with massive hydrops in one side of the thoracic cavity(10 case), with a small amount of effusion on one side(3 cases), with rib destruction and the shadow of the chest wall(7 case), in the mediastinal and subaxillary lymph nodes(1 cases), and with the invasion of other organs outside the lungs(4 cases). Conclusion CT fearures of SPL has revealed, it can provide information for clinical practice.
