In 9% of 78 normal computed tomographic examinations, the azygos vein was interposed between the posterior wall of the right-main or right-upper-lobe bronchi and lung in the azygoesophageal recess. Observation of the azygos vein on contiguous scans will generally allow a confident identification of this normal variant. Contrast enhancement will elucidate difficult cases.
在78例正常计算机断层扫描检查中，9%的病例奇静脉位于奇静脉食管隐窝内右主支气管或右上叶支气管后壁与肺之间。在连续扫描中观察奇静脉通常可以可靠地识别这种正常变异。增强扫描有助于明确诊断困难的病例。
