OBJECTIVE. The objective of this article is to discuss the anatomy, embryonic origin, normal variants, and various attachments of the ligament of Treitz. We also describe the pathologic processes that develop along the ligament of Treitz and the role of cross-sectional imaging in identifying these conditions.

CONCLUSION. The ligament of Treitz, also known as the suspensory ligament of the duodenum, is an important anatomic landmark in the abdomen. It is essential that radiologists understand the anatomic attachments, normal variants, and various pathologic conditions involving the ligament of Treitz as well as the role of cross-sectional imaging in the assessment of these conditions.

客观的。本文的目的是讨论Treitz韧带的解剖结构，胚胎起源，正常变异和各种附着。我们还描述了沿Treitz韧带发展的病理过程以及横截面成像在识别这些疾病中的作用。

结论。Treitz韧带（也称为十二指肠悬韧带）是腹部的重要解剖标志。放射科医生必须了解涉及Treitz韧带的解剖学附件，正常变异和各种病理状况，以及横截面成像在评估这些状况中的作用。
