目的就周围型小肺癌的高分辨CT表现进行探讨。方法通过对43例患者的影像学回顾性分析,使用Philips brilliance Power 6螺旋CT机,找出该病的影像学特点,对该病有一个系统的认识。结果本组43例患者中有32例通过HRCT清晰看到出现了锯齿状、棘状突起、细短毛刺等症状,其中86%患者具有以上1～2个征象。40例患者出现了直径<3cm的小肺癌,发生率达93%。本组无1例出现卫星灶征象,39例患者出现了胸膜凹陷征、血管聚集征,34例出现癌性淋巴管炎征象,3例可见肿瘤胸膜侧模糊小片影征象。16例支气管肺泡癌患者可见蜂窝征、磨玻璃征、分叶征、空泡征、支气管征等征象;3例小细胞癌患者出现了分叶、毛刺、空泡等征象;9例多见灶性坏死、深分叶征象,也可见血管聚集、毛刺、胸膜凹陷等征象;15例腺癌患者可见胸膜凹陷、毛刺、血管聚集、分叶等。结论对常规检查不能明确诊断的周围型小肺癌患者,应及时行HRCT检查,有助于明确该病的诊断。
Objective To investigate the high resolution CT findings of peripheral small lung cancer. Methods A retrospective analysis of 43 patients with a Philips brilliance Power 6 CT was used to identify the imaging features of the disease and to provide a systematic understanding of the disease. Results In the group of 43 patients, 32 cases showed symptoms of jerk, spicule and short and long burr clearly by HRCT. Among them, 86% had more than one or two signs. Forty patients had small lung cancers <3 cm in diameter, with a 93% incidence. No cases of this group showed signs of satellite lesions, pleural indentation in 39 patients showed signs of vascular aggregation of 34 cases of lymphangitic signs of cancer, 3 cases of visible tumor pleural side fuzzy small pieces of shadow signs. Sixteen patients with bronchial alveolar carcinoma showed signs of honeycomb, ground glass, lobulated, vacuolar, and bronchial signs. Three cases of small cell carcinoma showed lobulation, burr, The signs of necrosis and deep lobe were also observed. The blood vessels gathered, burr and pleural indentation were also seen. Fifteen patients with adenocarcinoma showed pleural indentation, burr, blood vessels and lobulation. Conclusions Patients with peripheral small lung cancer who can not be diagnosed by routine examination should be examined by HRCT in time, which helps to confirm the diagnosis of the disease.
