摘要:
目的:分析局灶性磨玻璃密度(f GGO)肺癌的CT表现,以提高诊断早期肺癌的准确率。方法:搜集经手术病理证实的、临床及CT资料完整的、表现为磨玻璃密度的肺癌病例34例,作回顾性分析,观察病灶大小、形态、边缘、密度及其他肺癌倾向征象,以及病灶在随访过程中的影像学变化。结果:34例患者中p GGO 7例,m GGO 27例,瘤肺界面清晰,病灶边缘可见分叶、毛刺,病灶内部可见空泡、支气管充气征,病灶周围可见胸膜凹陷征、血管集束征等。f GGO在随访过程中,病灶增大,密度增高,p GGO病灶内部出现实性成分,m GGO病灶内实性成分增多,病灶边缘出现分叶、毛刺,周围出现胸膜凹陷征、血管集束征等恶性征象。结论:f GGO肺癌的CT表现具有一定的特征性,CT随访对f GGO的良恶性鉴别具有较高的价值。
Abstract:
Purpose: To analyze CT manifestations of fGGO for improving diagnosis of early lung cancer. Methods: Retrospective analyze lung cancer cases presenting as fGGO confirmed by operation and pathology with complete clinical CT data, observe its size, shape, margin, density and other lung cancer signs, as well as imaging diversity during follow-up CT scan. Result: 34 cases included 7 pGGO and 27 mGGO, showed well-defined interface, lobulated border and spiculated margin vacuole sign and air bronchogram, surrounding with pleural indentation sign and blood vessel cluster sign. In follow up, larger size and higher percent of solid component were seen in fGGO, with more solid lesions in pGGO, larger size in mGGO, lobulated border and spiculated margin, pleural indentation sign and blood vessel cluster sign. Conclusion: CT manifestations of lung cancer as ground-glass opacity have certain characteristics, CT follow-up has high value to the identification between benign and malignant fGGO.
