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.
