目的：通过直接淋巴管造影（Direct lymphangiography，DLG）后CT成像，总结归纳胸部碘油异常分布的影像类型，并分析不同类型胸部碘油沉积患者的临床和影像特征。方法：回顾性分析我院DLG后CT图像中显示有胸部碘油异常分布的151例患者（男84名，女67名）的临床和影像资料。根据胸部淋巴管解剖和影像表现，将其分为4组。对4组病例的临床和影像指标组间差异应用Pearson χ2检验法。结果：151例DLG后CT成像显示胸部碘油异常分布的患者中，A组16例（10.6%），B组91例（60.3%），C组15例（9.9%），D组29例（19.2%）。4组间的临床和影像学征象差异有统计学意义。结论：DLG后CT成像可以清晰显示胸部碘油沉积及其他胸部异常征象。根据碘油异常分布部位不同总结归纳了4种不同类型，为胸部淋巴管病变的诊断及鉴别提供更多影像学依据。
Abstract
Objective: To retrospectively summarize a novel classification system by CT after direct lymphangiography in 151 patients with lipiodol abnormal distribution in chest, and the clinical and CT features of different types were analyzed. Methods: A total of 151 patients(including 84 males and 67 females) exhibiting lipiodol abnormal distribution in chest CT after direct lymphangiography were retrospectively reviewed. The clinical date and CT findings were retrospectively reviewed. These patients were classified into 4 types according to chest lymphatic anatomy and CT findings. The clinical data and image findings correlation among the 4 groups were compared using Pearson χ2 test. Results: After direct lymphangiography, lipiodol was found abnormal distribution in chest CT in 151 patients. Among them, Group A had 16 cases(10.6%), Group B had 91 cases(60.3%), Group C had 15 cases(9.9%) and Group D had 29 cases(19.2%). There were significant differences in clinical data and CT findings among the 4 types. Conclusion: CT imaging after direct lymphangiography is effective to observe lipiodol abnormal distribution and other chest abnormal findings. This study summarized a classification of 4 different types according to the lipiodol abnormal distribution in chest, which provide more information for clinical diagnosis and differential diagnosis for chest lymphatic disease.
