摘要
目的 :探讨CT增强、CTA对肺隔离症的诊断价值。材料和方法 :对经手术、主动脉造影证实的 2 3例肺隔离症患者行CT平扫及增强扫描。结果 :含气体或液体的囊肿或软组织肿块 18例。病变为肺气肿所包裹 5例。 18例结节或肿块平扫密度均匀 ,增强扫描 8例表现为无增强 ,5例为薄壁增强 ,5例为厚壁增强。螺旋CT显示异常主动脉供血血管比率( 83 % )高于普通CT( 5 9% ) ,4例CTA清楚显示供血动脉。结论 :肺隔离症的主要CT表现是囊肿、结节和肿块 ,增强CT扫描有助于显示结节和肿块内部的囊性成分及主动脉异常供血血管。CTA能立体显示供血动脉的起源、行程。
Purpose:To evaluate the diagnostic value of contrast enhanced CT and CTA in bronchopulmonary sequestration. Materials and Methods:23 patients of pulmonary sequestration proved by surgery or angiography were studied. Results:CT scans showed that sequestration with cysts containing air or fluid, or soft tissue masses was in 18 cases, lesion with emphysematous lung surrounded in 5,and nodules, masses were homogeneous density in 18. Enhanced scan showed no enhancement in 8 patients ,thin wall enhancement 5 ,thick wall enhancement 5. Spiral CT showed more anomalous systemic artery(83%) than conventional CT(59%).CTA successfully delineated the origin and course of anomalous systemic artery. Conclusion:The main CT appearance of pulmonary sequestration is cyst, nodule and mass. Enhanced CT can demonstrate the cystic contents in nodules and masses, and also be helpful to identify anomalous systemic artery. Spiral CT angiography can show origination and course of the anomalous systemic artery by three dimension.
