The goal of our study was to investigate the appearance of the medial umbilical folds on CT.
We retrospectively reviewed the CT images of 30 consecutive patients with massive ascites. In addition, we inspected the inner pelvic wall in cadavers.
The medial umbilical folds were well recognized on CT in 21 of 30 patients, bilaterally in 20 and unilaterally in 1. In four patients the folds were undetectable after the ascites resolved. The CT findings were supported by those studied in cadavers, in which the folds were recognized as a peritoneal reflection in 13 of 20.
We concluded that medial umbilical folds could be commonly visualized on CT when ascites was present.
我们研究的目的是调查CT上脐内侧襞的表现。
我们回顾性分析了30例连续性大量腹水患者的CT图像。此外，我们还对尸体的盆腔内壁进行了检查。
30例患者中21例在CT上能很好地识别出脐内侧襞，双侧20例，单侧1例。4例患者腹水消退后襞无法检测到。CT表现得到了尸体研究的支持，20例中有13例的襞被识别为腹膜反折。
我们得出结论，当存在腹水时，脐内侧襞在CT上通常可以看到。
