摘要
目的通过对35例肺部单发局限性磨玻璃密度影(FGGO)资料进行回顾性分析,探讨FGGO影像学的表现对临床诊断及治疗的指导价值。方法35例直径≤20mm的FGGO病例,在HRCT随访数月后(平均1～3个月),7例病变消失或明显吸收,考虑为炎症;28例病变持续存在,经胸腔镜活检或肺叶切除后送病理诊断。结果28例FGGO,经确诊支气管肺泡癌(BAC)16例,腺癌5例,非典型腺瘤样增生(AAH)4例,局灶性机化性肺炎3例。对确诊28例FGGO影像表现进行分析,21例恶性病例中,18例病灶≥10mm,占85.71%(18/21),可见一种或多种恶性征象的有16例,占76.19%(16/21);有实性成分的15例,占71.43%(15/21)。说明持续存在的FGGO的大小、边缘及内部征象是否含有实性成分,与病变良、恶性及其预后有明显相关性。结论持续存在的直径≥10mm,有恶性征象或含有实性成分的FGGO为早期腺癌或癌前病变的表现,临床应早期活检定性,以指导治疗。
Objective To discuss the imaging of focal groundglass opacity （FGGO） in clinical diagnosis and treatment. Methods The clinical data of 35 cases of such patient were analyzed retrospectively. 35 cases less than 2cm were followed up with HRCT. 7 cases had disappeared as inflammation. 28 cases were further biopsy with VATS or pulmonary lobectomy. Results 28 FGGO were diagnosed as bronchiotoalveolar carcinoma （BAC） in 16 cases, adenocarcinoma in 5 cases, atypical adenomotous hyperplasia （AAH） in 4 cases and local inflammation in 3 cases. The lesion in 18 cases was more than 10ram in size with one or more symbols of malignancy in 16 cases. There were 15 cases in mass. Conclusion The results showed that lasting lesion, edge, mass, symbol inside might be related with benign or malignancy. The lesion 〉 10mm with FGGO should be performed in biopsy.
