奇叶是一种正常变异,发生率0.4%。正常胸片上奇叶透过度与肺相同,但少数变可密度增高而拟似肺或纵隔病变。研究3年中7例奇叶密度增高的胸片和CT 检查,分析正常情况下奇叶密度增高的原因。3年共见到53例奇叶。按奇静脉裂位于右肺尖外、中、内部分的不同将奇叶划分为A、B、C 三型。胸片示7(男5,女2)例奇叶密度增高,患者年龄2～82岁。其中B 型3例,提示为肺内病变;C 型4例,提
Qi Ye is a normal mutation, the incidence of 0.4%. Normal chest X-ray leaflets with the same degree of transparency, but a few can be increased density and pseudo-lung or mediastinal lesions. Seven cases of abnormal leaf density increased chest X-ray and CT examination in 3 years to analyze the reasons for the increase of odd leaf density under normal circumstances. 3 years saw a total of 53 odd leaves. According to azygos vein located in the right apex, in the different parts of the odd leaves will be divided into A, B, C three types. Chest radiograph showed 7 (male 5, female 2) cases of odd leaf density increased, patients aged 2 to 82 years. Of which 3 cases of type B, suggesting lung lesions; C type 4 cases, mention
