摘　　要：目的探讨伴有薄壁空腔形成的周围型肺腺癌的CT表现,提高对该病的诊断准确率。方法回顾性分析21例经病理证实的伴有薄壁空腔形成的周围型肺腺癌的CT影像资料,对其进行总结、分析。结果 21例中有14例位于双肺中上叶,13例实性病灶呈类椭圆形,边缘可见分叶征、毛刺征、血管集束征和胸膜增厚、牵拉的例数分别为18、15、11和3。所有空腔病灶的壁较薄,平均(2.04+1.02)mm,厚度在2mm以下者有11例;17例空腔病灶位于实性病灶的周边部,12例空腔壁厚度较均匀,9例可见壁结节形成;空腔内血管穿行征及分隔形成者分别为8例和5例。结论伴有薄壁空腔形成的周围型肺腺癌的CT表现具有一定特征,即病灶多位于中上肺、实性病灶多呈类椭圆形,边缘多见分叶征、毛刺征、血管集束征等恶性征象;而空腔病灶多位于实性病灶的周边部,空腔壁较薄且厚度较均匀,壁结节少见。Objective To discuss the CT features of peripheral lung adenocarcinoma with thin-walled cavity to improve the diagnosis accuracy. Methods The CT images of 21 cases with peripheral lung adenocarcinoma with thin-walled cavity confirmed by pathology were retrospectively analyzed to summarize the CT features. Results In 21 cases, there are 14 cases located at both upper and middle lobes. The solid lesions of 13 case showed as oval shape, and the lobulation, speculation, vessel convergence sign and pleural change signs were observed in 18 cases, 15 cases, 11 cases and 3 cases respectively. All the cavitary lesions were with thin-walled, and the average thickness of the wall was （2. 04 ± 1.02） mm. There were 11 lesions with thickness of the wall less than 2mm. The cavity located at the periphery of the solid lesions were observed in 17 cases, 12 cases of the cavity with even wall, and 9 cases with mural nodule. 8 cases showed vessel in the cavity and 5 cases showed there were septum in the cavity. Conclusion Peripheral lung adenocarcinoma with thin-walled cavity has some CT features, such as the lesions more likely located at the upper and middle lobes, the solid lesions more likely presented as oval shape, and there were lobulation, speculation and vessel convergence on the margin; while the cavitary lesions more likely located at the periphery of the solid lesions, and the wall of the cavity is even, the mural nodules less likely observed.
