The CT examinations of the pelvis in 200 females were reviewed to assess the frequency and significance of finding air in the vagina. Small amounts of air seen on only one section without distention of the vagina were common, occurring in 11% of our patients. Distention of the vagina with air and visualization on more than one image was found only with enterovaginal fistula and in those patients studied with a tampon in place. These two entities are easily distinguished by the symmetry of the latter.
回顾了200名女性的骨盆CT检查结果，以评估阴道内出现气体的频率及其意义。仅在一个层面上发现少量气体且阴道无扩张的情况很常见，在我们的患者中占11%。仅在肠阴道瘘患者以及阴道内放置棉塞进行检查的患者中发现阴道内有气体扩张且在多个图像上可见。通过后者的对称性可轻松区分这两种情况。
