The hepatoduodenal ligament is frequently involved by conditions affecting the portal triad and surrounding structures, including a vast array of non-neoplastic conditions. Due its unique location between the retroperitoneum and the peritoneal space, the hepatoduodenal ligament is also targeted by inflammatory conditions involving the retroperitoneum and the liver. Finally, the presence of lymphatics and of the biliary tracts makes the hepatoduodenal ligament a route of spread for a variety of infections. The purpose of this pictorial essay is twofold: to review the cross-sectional radiological anatomy and variants of the structures within the hepatoduodenal ligament, and to illustrate the non-neoplastic conditions that may arise within the hepatoduodenal ligament.
Familiarity with these specific entities and their cross-sectional imaging findings is fundamental for a more accurate diagnosis.
肝十二指肠韧带经常受到影响门三联症和周围结构的各种条件,包括大量的非肿瘤性条件。由于其位于腹膜后和腹膜腔之间的独特位置,肝十二指肠韧带也是涉及腹膜后和肝脏的炎症性疾病的靶点。最后,淋巴管和胆道的存在使得肝十二指肠韧带成为多种感染的传播途径。本影像学专题论文有两个目的:一是回顾肝十二指肠韧带内结构的横断面放射解剖学和变异,二是说明可能发生在肝十二指肠韧带内的非肿瘤性疾病。
熟悉这些特定实体及其横断面成像表现对于更准确的诊断至关重要。
