| 目的 探讨原发性肺淋巴上皮瘤样癌的CT特征。方法 回顾性分析经手术和病理证实的39例肺淋巴上皮瘤样癌的临床病理及CT资料。结果 39例均为肺内单发病灶，最大径1.12~9.55 cm，其中17例中央型、22例外周型，肿瘤好发于右肺中叶及左肺下叶，共27例（27/39，69.23%）。31例CT平扫表现为均匀等密度肿块，2例见小斑片状低密度区，3例可见细点样钙化，3例出现空洞；增强扫描示均匀强化28例，出现小斑片状坏死8例，出现血管或支气管包埋征15例。肿块呈分叶状25例，边缘可见细毛刺23例，胸膜凹陷征8例。23例出现淋巴结转移。结论 原发性肺淋巴上皮瘤样癌CT表现既具有淋巴瘤的特征，也具有与其他类型肺癌相似之处。 |

| Objective To investigate the CT features of primary pulmonary lymphoepithelioma-like carcinoma (LELC). Methods Clinical information and CT findings were analyzed retrospectively in 39 patients with surgical pathology conformed pulmonary LELC. Results Totally 39 cases had single lung mass, the biggest diameters ranging from 1.12 cm to 9.55 cm. Among them 17 central tumors and 22 peripheral tumors were identified. Tumors occurred more frequently in right middle lobe and left lower lobe (n=27). CT pulmonary LELC showed homogeneously isodensity in 31 patients, small patchy low density area in 2 patients and punctate calcification in 3 patients and cavity in 3 patients. CT contrast-enhanced scans showed homogeneously enhanced in 28 patients, small patchy necrosis in 8 patients, vascular or bronchial encasement in 15 patients. 25 cases were lobulated mass, 23 cases showed fine burr edge, and 8 cases had pleural indentation sign. Lymphadenopathy was found in 23 patients. Conclusion Primary pulmonary LELC has characteristics of both lymphoma and the other types of lung cancer on CT findings. |
