The present case represents the second report of an aberrant azygos lobe, following Adachi's (1940) first case. The authors describe the characteristic features of an azygos lobe observed in the right lung of a 65-year-old man as well as the extra-pulmonary course of the bronchial arteries and veins. The literature on the azygos lobe reported in Japan and the extremely rare cases in which an azygos lobe has been found on the left side, are summarized. Upon dissecting the pulmonary parenchyma, it became clear that the azygos lobe was supplied by definitive segmental branches (B1a and B2a, A1a and A2a, and V1a and V2a) of the tracheobronchial tree and pulmonary vessels. The authors review and summarize the patterns of the segmental bronchi and vessels in the azygos lobe and also discuss the development of this anomaly.
本病例是继安达智（1940年）首例报道之后，关于奇叶异常的第二例报告。作者描述了在一名65岁男性右肺中观察到的奇叶的特征，以及支气管动静脉的肺外走行。对日本报道的有关奇叶的文献以及在左侧发现奇叶的极其罕见的病例进行了总结。在解剖肺实质时发现，奇叶由气管支气管树和肺血管的明确节段分支（B1a和B2a、A1a和A2a以及V1a和V2a）供血。作者回顾并总结了奇叶中节段支气管和血管的模式，并讨论了这种异常的发育情况。
