目的 分析孤立型细支气管肺泡癌 (SBAC)的CT征象特点 ,以提高其CT诊断准确性。方法 回顾性分析 1990 -0 1～1999-0 3经手术病理证实的 39例SBAC的CT表现 ,并与其它类型的直径≤ 3mm的 48例周围型肺癌进行对照分析。结果 CT显示分叶 32例 ,毛刺 33例 ,胸膜凹陷 2 5例 ,血管集束 14例 ,病灶内空泡和 /或细支气管充气 18例 ,磨玻璃样改变 8例。结论 SBAC的特征性CT表现 :( 1)空泡和 /或细支气管充气 ;( 2 )粗长毛刺 ;( 3)磨玻璃样改变。认识SBAC的CT表现 ,有助于提高其诊断水平。
Objective To analyze the CT features of isolated bronchioloalveolar carcinoma (SBAC) to improve the diagnostic accuracy of CT. Methods The CT findings of 39 patients with pathologically confirmed SBAC from 1990 to 1999-0 3 were retrospectively analyzed and compared with 48 other peripheral lung cancers of other types with a diameter of ≤ 3 mm. Results CT showed lobectomy in 32 cases, burr in 33 cases, pleurodesis in 25 cases, vascular bundles in 14 cases, lesions in the vacuoles and / or bronchioles in 18 cases, ground glass-like changes in 8 cases. Conclusions The characteristic CT findings of SBAC are: (1) vacuoles and / or bronchioles, (2) rough long burr, and (3) ground glass changes. Knowing the CT findings of SBAC will help to improve its diagnosis.
