CT淋巴管成像及胸部平扫CT诊断乳糜痰

目的 观察直接淋巴管造影(DLG)后CT淋巴管成像(CTL)及平扫CT诊断乳糜痰的价值。方法 回顾性分析17例乳糜痰患者CTL及胸部平扫CT资料,观察淋巴管异常及胸部其他异常表现。结果 17例CTL均见碘化油异常沉积,分布于颈根部、纵隔区、胸腔和胸壁,以颈静脉角区最为常见,部分可见肺部碘化油反流及多处淋巴管扩张;胸部平扫CT显示肺、胸膜、纵隔及心包等多处异常,以支气管血管束增粗最为常见。结论 CTL对诊断乳糜痰有一定价值;胸部平扫CT可显示乳糜痰患者肺及胸部其他结构异常改变。

CT lymphangiography and chest non-contrast CT for diagnosis of chyloptysis

Objective To observe the value of CT lymphangiography (CTL) followed direct lymphangiography (DLG) and chest non-contrast CT for diagnosis of celiac chyloptysis sputum. Methods CTL and chest non-contrast CT data of 17 chyloptysis patients were retrospectively analyzed, lymphatic vessel abnormalities and other chest abnormal manifestations were observed. Results Abnormal deposits of lipiodol on CTL were noticed in all 17 cases, distributed in different parts of the cervical root, mediastinal region, thoracic cavity and chest wall, most often in the jugular venous angle regions. Reflux of lipiodol were found in the lungs in few cases, while dilatation of lymphatic ducts were observed in some cases. Chest non-contrast CT showed multiple abnormalities, including intrapulmonary, pleura, mediastinum and pericardium abnormalities, and bronchial vascular bundles was the most common one. Conclusion CTL was valuable for diagnosis of chyloptysis. Chest non-contrast CT could display lung and other chest structure abnormalities of chyloptysis patients.
