摘　　要：目的探讨直接淋巴管造影(DLG)后CT及增强CT诊断乳糜性胸腔积液的价值。方法回顾性分析2011年7月1日至2023年6月30日经临床确诊为乳糜性胸腔积液患者的临床及影像学资料共16例,所有患者均行DLG后CT和CT增强检查。结果DLG后CT及增强CT可见胸内异常表现,包括对比剂分布异常,肺脏异常、胸膜异常、纵隔异常和骨的异常;6例患者可见肺实变,2例患者可见小叶间隔增厚,5例患者可见支气管血管束增粗,4例患者可见胸膜增厚,胸椎和肋骨可见不同程度的骨质破坏和密度减低,4例患者可见纵隔淋巴结强化。结论DLG后CT和增强CT可明确胸部病变的特征,对诊断乳糜性胸腔积液有重要的价值。Objective To explore the value of CT and enhanced CT after direct lymphangiography in diagnosing chylothorax.Methods The clinical and imaging data of 16 patients diagnosed with chylothorax from July 1,2011 to June 30,2023 were retrospectively analyzed,and all of them underwent post-direct lymphangiography CT and CT-enhanced examination.Results A large number of intrathoracic abnormalities could be seen on post-direct lymphangiography CT and CT enhancement,including abnormal contrast distribution,lung abnormalities,pleural abnormalities,mediastinal abnormalities,and bone abnormalities;solid lung lesions could be seen in 6 patients,lobular septal thickening in 2 patients,bronchial vascular bundles thickening in 5 patients,pleural thickening in 4 patients,and different degrees of bone destruction and hypodensity of thoracic vertebrae and ribs,and mediastinal enhancement could be seen in 4 patients.Mediastinal enhancement was seen in 4 patients.Conclusion Direct lymphangiography followed by CT and enhanced CT can clarify the characteristics of chest lesions,which is valuable for the diagnosis of chylothorax.
