【摘要】：目的:分析肺内孤立性薄壁囊腔型肺癌的螺旋CT影像特征,提高对该病的诊断水平。方法:本研究中把螺旋CT影像上表现为囊腔状且其75%以上囊壁厚度小于4 mm的肺癌定义为薄壁囊腔型肺癌。回顾性分析13例经手术或穿刺病理证实的肺内孤立性薄壁囊腔型肺癌的螺旋CT影像资料。结果:本组13例病例中,10例呈现囊腔壁厚度不均,9例可见短毛刺征,7例可见壁结节形成,增强扫描时壁结节呈不同程度对比强化,7例可见胸膜凹陷/增厚等异常改变,5例呈囊内壁不光滑及腔内可见血管穿行,3例病灶边缘可见分叶征;病理结果显示其中11例为腺癌,1例为支气管肺泡癌,1例为鳞癌。结论:肺内孤立性薄壁囊腔型肺癌的影像学表现具有一定特征性,主要表现为囊壁厚度不均、短毛刺征、壁结节形成、胸膜改变及囊内壁不光滑等。
[Abstract]:Objective: to analyze the spiral CT features of solitary lung cancer with thin walled cystic cavity. Methods: in this study, lung cancer with 75% or more thickness of cystic wall was defined as thin-walled cystic lung cancer on spiral CT images. A retrospective analysis of 13 cases was performed or perforated. Results: in this group of 13 cases, 10 cases showed uneven wall thickness of cystic cavity, 9 cases showed short burr sign and 7 cases showed wall nodule formation. On contrast enhancement, 7 cases showed abnormal changes such as pleural depression / thickening, 5 cases showed non-smooth inner wall of the capsule and 3 cases showed lobulation sign at the margin of the lesion. The pathological results showed that 11 cases were adenocarcinoma and 1 case was bronchoalveolar carcinoma and 1 case was squamous carcinoma. Conclusion: the imaging features of pulmonary solitary parenchyma cystic type lung cancer are characterized by uneven thickness of cystic wall and short burr sign. Mural nodule formation, pleural changes and intracystic wall unsmoothness.
