Objective To explore the application of multi-slice spiral CT reconstruction in cystic lung cancer and its pathological correlation. Method Retrospectively analyzed the multi-slice spiral CT and pathological data of 28 cases of cystic lung cancer patients who were treated in our hospital from March 2011 to July 2016. Result Multi-slice spiral CT reconstruction showed that 16 cases of cystic lung cancer foci located in the right lung, 12 cases in the left lung, 16 cases in the two upper lungs, and 12 cases in the lower lung. The mean tumor diameter was (33.45±13.26) mm, and the mean tumor center was (21.47±8.24) mm from the pleura, the mean cyst diameter was (20.11±10.36) mm. The results of Mario classification showed that, there were 8 cases of typeⅠ, 2 cases of type Ⅱ, 8 cases of type Ⅲ and 10 cases of type Ⅳ. A single cyst in 12 cases, multiple cysts in 16 cases, cysts in the separation of 16 cases. 26 cases of vascular bundles sign, of which 6 cases showed brachial blood vessel growth. Tumor week patch film 14 cases. Compared with the results of the first CT, the last CT follow-up showed: the diameter of the cyst decreased in 3 patients, the diameter of extranodular nodules increased in 5 patients, and the density of extracapsular nodules increased in 4 patients. In the group of patients with adenocarcinoma in 25 cases, of which 20 cases of invasive adenocarcinoma, 3 cases of adenosquamous carcinoma, 2 cases of adenocarcinoma in situ. 6 cases of cysts showed tumor cells were coated, 2 cases of central tumor necrosis, 6 cases of pulmonary bullae contained in the tumor, 10 cases of bronchiectasis in the tumor, and 26 cases of tumor nourish blood vessels. Conclusion Cystic lung cancer with invasive adenocarcinoma is the most common, multi-slice spiral CT examination results in a certain characteristic performance, the pathological basis may be based on the original cyst, secondary to lung cancer, bronchial tumor or the destruction of alveoli structure related.%目的 分析多排螺旋CT重建在囊腔型肺癌中的应用及病理对照.方法 回顾性分析本院2011年3月至2016年7月收治的28例囊腔型肺癌患者的多排螺旋CT重建结果及术后病理结果.结果 多排螺旋CT重建结果显示,囊腔型肺癌癌灶位于右肺16例,位于左肺12例,位于两上中肺16例,位于两下肺12例.平均肿瘤直径为(33.45±13.26)mm,平均癌灶中心距胸膜(21.47±8.24) mm,平均囊腔直径为(20.11±10.36)mm.Mario分型评定结果显示:Ⅰ型8例,Ⅱ型2例,Ⅲ型8例,Ⅳ型10例.单个囊腔12例,多个囊腔16例,囊腔内出现分隔16例.血管集束征26例,其中6例呈现肿瘤周围气管血管束生长.斑片/条索影14例.与首次CT结果相比,末次CT随访结果显示:囊腔直径缩小3例,囊腔外结节直径增大5例,囊外结节密度增高4例.入组患者中腺癌25例,其中浸润性腺癌20例,腺鳞癌3例,原位腺癌2例.囊腔表面被覆肿瘤细胞6例,肿瘤中央坏死2例,瘤内含肺大疱6例,瘤内支气管扩张10例,瘤内见滋养血管26例.结论 囊腔型肺癌以浸润性腺癌最多见,在多排螺旋CT检查结果中具有一定的特征性表现,其病理学基础可能与在原囊腔基础上继发性出现肺癌、支气管腔内肿瘤或破坏肺泡结构有关.
