The Findings of Multi-Slice CT in Pripheral Pulmonary Hamartoma
-
摘要: 目的:探讨肺错构瘤的多层螺旋CT(MGCT)表现,以提高CT诊断水平。方法:回顾性分析经手术病理证实的32例肺错构瘤的MGCT平扫及22例MGCT动态增强扫描的特点。结果:MGCT上所有结节边缘光滑。结节内含有脂肪密度(无钙化)的12例,占37.5%,既有脂肪又有钙化的8例,占25.0%,只有钙化的2例,占6.3%。增强扫描(22例)强化值<20HU的20例,占90.9%,强化形态呈间隔状强化16例,占72.7%。结论:肺错构瘤的MSCT表现有一定的特征性,边缘光滑、结节内含有脂肪和钙化有助于诊断,动态MGCT增强扫描有助于与周围型肺癌的鉴别诊断。Abstract: Objective: To research the appearances of multi-slice CT(multi-slice CT MSCT)in pulmonary hamartoma so as to improve the CT diagnostic accuracy. Methods: The CT and pathological findings of 32 cases of pulmonary hamartoma were analyzed. Dynamic contrast enhancement MSCT scanning were performed in 22 cases. All cases were confirmed by surgical operation and pathology. Results: All hamartomas had smooth edge on MSCT. Focal fat without calcification inside were present in 12 of 32 cases(37.5%), focal fat and calcification inside in 8 of 25cases (25%), calcification without fat inside in 2 of 32 cases (6.25%). The CT contrasted value was less than 20 Hu in 20 of 22 cases (90.9%). Contrast-enhancing septa were present in 16 of 22 cases(72.7%). Conclusion: Some specific MSCT features, including smooth edge, calcification and fat inside, are useful for diagnosis of pulmonary hamartoma. Dynamic contrast enhancement MSCT scanning is useful for differentiating pulmonary hamartoma with peripheral lung carcinoma.
