摘要
目的研究多层螺旋高分辨率CT(HRCT)对直径小于2Cm的周围型肺癌的诊断价值。方法选取从2006年8月～2008年6月诊断为肺癌,并经病理证实的29例病灶直径不到2cm的周围型肺鳞癌患者资料进行分析,其中男24例,女5例。年龄在45～87岁之间(平均60.6岁)。其中位于右肺上叶的12例,右肺中叶的2例,右肺下叶的4例,左肺上叶的8例,左肺下叶的3例。在这些病例中有15例为中分化,14例为重度分化。结果 HRCT病灶无1例钙化(0%),空洞形成1例(3.4%),空气支气管征5例(17.2%),毛玻璃高密度影1例(3.4%),毛刺8例(27.6%),分叶8例(27.6%),边界不规则19例(65.5%),胸膜凹陷14例(48.3%),周围肺气肿19例(65.5%)见图1-3,卫星灶1例(3.4%)。结论高分辨螺旋CT(HRCT)能够清晰显示直径小于2cm周围型肺癌的形态,在周围型鳞癌的诊断中有重要价值。
Objective To evaluate the value of HRCT in diagnosis of small（less than 2cm in maximum dimension）peripheral lung cancer. Methods Subjects consisted of 29 consecutive pathologically proven cases of peripherally located squamous cell carcinoma that were less than 2cm in maximum dimension, detected from August 2006 through June 2008. The cases included 24 men and 5 women, ranging in age from 45 to 87 years （mean age, 60.6 years）, The tumors were located in the right upper lobe （n = 12）, right middle lobe （ n = 2）, fight lower lobe （ n = 3 ）, left upper lobe （ n = 8 ）, and left lower lobe （ n = 2）. There were 14 moderately differentiated and 13 poorly differentiated squamous cell carcinomas. Results HRCT images showed no calcification in any case （0%） ;cavity in 1 case （3.4%） ; air bronchogram in 5 cases （17.2%） ; ground -glass attenuation in 1 case （3.4%） ; speculation in 8 cases （27.6%） ; notching in 8 cases （27.6%） ; irregularity in 19 cases （65.5%） ;pleural indentation in 14 cases （48.3%） ; pulmonary emphysema in 19 cases （65.5%） ; and satellite lesions in 1 case （3.4%）. Conclusions HRCT images can show irregularity, surrounding pulmonary emphysema,and absence of calcification of small（less than 2 cm in maximum dimension）peripheral lung cancer, these findings was especially important in establishing diagnosis of small （less than 2 cm in maximum dimension）squamous cell carcinoma.
