The hook sign is a radiologic finding best appreciated on a sagittal view of the celiac artery with computed tomography (CT) that indicates compression of the celiac artery. It refers to the hooked-shape of the proximal celiac artery caused by extrinsic compression by the median arcuate ligament. When seen in a patient with concurrent abdominal symptoms, it suggests median arcuate ligament syndrome (MALS). We saw the sign in a 15-year-old male via duplex ultrasonography and abdominal CT. He underwent laparoscopic release of the median arcuate ligament and had full resolution of his symptoms at follow-up.
钩状征是一种影像学表现，在腹腔动脉的矢状位 CT 上最佳，表明腹腔动脉受压。它指的是近端腹腔动脉由于正中弓状韧带的外在压迫而呈钩状。当在伴有腹部症状的患者中看到这种征象时，提示正中弓状韧带综合征（MALS）。我们通过双功能超声和腹部 CT 在一名 15 岁男性中看到了该征象。他接受了腹腔镜下正中弓状韧带松解术，随访时症状完全缓解。
