目的研究以肺叶肺段实变为主要表现的细支气管肺泡癌CT表现。方法回顾性分析6例实变型细支气管肺泡癌的CT表现,研究CT在实变型细支气管肺泡癌诊断中的价值。结果斑片实变影5例(83%),充气支气管征5例(83%),管腔可正常或狭窄变形;周围磨玻璃征5例(83%),边界可模糊或清晰;4例增强扫描,强化不明显3例(75%),其血管造影征阳性。结论边界清楚的磨玻璃征、脂肪肝样强化的血管造影征表现较有特征性。大部分细支气管肺泡癌不具有特征性表现,需结合临床资料进行综合分析。 Objective To study CT manifestations of bronchioloalveolar carcinoma (CTL) with the main manifestation of pulmonary lobectomy. Methods The CT findings of 6 cases of solid bronchioloalveolar carcinoma were retrospectively analyzed. The value of CT in the diagnosis of solid bronchioloalveolar carcinoma was studied. Results In 5 cases (83%), 5 cases (83%) had inflatable bronchogenic signs and the lumen was normal or stenosed. The surrounding vitreous signs were obscure or clear in 5 cases (83%) and 4 Enhanced scanning, enhancement was not obvious in 3 cases (75%), its positive angiography. Conclusions Clear glass frit with clear boundary and fatty liver enhanced angiography show more characteristic. Most bronchioloalveolar carcinoma does not have the characteristic manifestations, need to combine the clinical data for comprehensive analysis.
