目的 探讨弥漫实变型细支气管肺泡癌 (DCBAC)的HRCT特征和动态变化特点。资料与方法 回顾分析经病理证实的 7例DCBAC的CT和HRCT表现 ,3例行 3～ 4次CT随访观察。分别记录病变范围、形态表现、动态变化。结果 叶、段型肺实变 7例 ,伴“枯树枝征”4例 ,“蜂窝征”4例 ,叶间裂膨隆 5例 ,磨玻璃密度影 6例和腺泡结节 7例。动态变化 :肺实变范围扩大 ,原为腺泡结节和 /或磨玻璃密度影的区域发展为肺实变。结论 多发的叶、段实变伴“蜂窝征”、叶间裂膨隆和远离实变区的腺泡结节和磨玻璃密度影是DCBAC的特征性表现 ;结合动态变化有助于DCBAC的诊断
Objective To investigate the characteristics and dynamic changes of HRCT in diffuse solid type bronchioloalveolar carcinoma (DCBAC). Materials and Methods Retrospective analysis of pathologically confirmed 7 cases of DCBAC CT and HRCT performance, 3 cases were 3 to 4 CT follow-up observation. Respectively record the extent of lesions, morphological manifestations, dynamic changes. Results Seventeen cases of pulmonary and segmental pulmonary consolidation, four cases of syndrome of dead branches, four cases of “honeycomb syndrome”, five cases of rupture of interlobar, six cases of ground glass density and seven cases of acinar nodules. Dynamic changes: Expansion of the range of lung consolidation, the original area of acinar nodules and / or ground glass density developed into lung consolidation. Conclusions The frequent DCBAC is the characteristic manifestation of DCBAC in multiple leaf segments and real consolidation with “honeycomb syndrome”, the bulbar interlobar rupture and acinar nodules and ground glass density away from the consolidation zone. It is helpful to diagnose DCBAC in combination with dynamic changes
