| 目的 分析肺叶内型肺隔离症的CT表现。 方法 回顾性分析38例肺叶内型肺隔离症,其中27例直接接受平扫加增强扫描,8例平扫疑为肺隔离症,后接受增强扫描,3例平扫疑为其他疾病,后接受增强扫描;并进行图像重建,记录病变的肺内表现、供血动脉起点,并测量供血动脉直径。 结果 肺内表现:最常见表现为实变合并囊变(n=20)及支气管扩张合并气肿(n=15)。血管表现:胸主动脉分支或肋间动脉供血时(n=25),肺隔离症发生于左肺下叶16例,右肺下叶9例;腹主动脉或腹腔干分支供血时(n=13),发生于左肺下叶4例,右肺下叶9例。 结论 肺叶内型肺隔离症具有特征性CT表现,当平扫发现支气管扩张合并气肿或囊变合并实变时,应注意肺隔离症存在的可能,并行增强扫描。 |

| Objective To analyze the CT features of intrapulmonary sequestration (IPS). Methods CT features of 38 patients with IPS were retrospectively reviewed. Twenty-seven patients underwent enhanced CT directly, 8 were suggested to undergoing enhanced CT after being suspected PS with plain scanning, 3 were supposed to undergo enhanced scan after being suspected with other diseases with plain CT. The images were reconstructed. The intrapulmonary appearances, the origin and the diameter of feeding arteries were recorded. Results The most common appearances in lung included consolidation combined cystic change (n=20) and bronchiectasis combined emphysema (n=15). In 25 patients with feeding artery from thoracic aorta, IPS located in the left lower lobe in 16 patients, in the right lower lobe in 9 patients. When the feeding artery was from abdominal aorta or celiac trunk (n=13), IPS located in the left lower lobe in 4 patients, in the right lower lobe in 9 patients. Conclusion CT manifestations of IPS are characteristic. Consolidation combined cystic changes or bronchiectasis combined emphysema on plain CT can indicate IPS, and then enhanced scan should be suggested. |
