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.
Abstract
Objective To explore the value of CT and enhanced CT after direct lymphangiography in diagnosing chylo-thorax.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 examina-tion.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 vas-cular bundles thickening in 5 patients,pleural thickening in 4 patients,and different degrees of bone destruction and hypo-density 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 character-istics of chest lesions,which is valuable for the diagnosis of chylothorax.
