目的：目的：分析胃腺癌肠转移的螺旋CT表现。方法：收集23例胃腺癌肠转移患者的螺旋CT资料。结果：18例肠壁呈内高外低靶向增厚，呈多个长节段，增强内层进行性增厚。15例（65%）累及多个部位，其中升结肠（n = 12）和直肠（n = 11）是最常见的两个部位。腹膜癌病（n = 15，65%）和肠梗阻（n = 14。61%）是常见的相关发现。原发灶以可塑性胃炎为主（n = 16），低分化腺癌伴或不伴印戒细胞分化者（n = 14）。最常见的表现为靶样长节段壁增厚，螺旋CT上有特征性的厚内强化层。
Purpose: The purpose of this work was to describe the helical CT findings of intestinal metastasis from gastric adenocarcinoma,Method: Twenty-three patients with intestinal metastasis from gastric adenocarcinoma found at helical CT were included. CT findings and clinical and pathologic data were reviewed.Results: The most common characteristic finding was target-like concentric bowel wall thickening (thick inner high-outer low, n = 18) involving multiple long segments with progressive thickening of the enhancing inner layer. Fifteen cases (65%) involved multiple sites, and the ascending colon (n = 12) and rectum (n = 11)were the two most common sites. Peritoneal carcinomatosis (n = 15, 65%) and bowel obstruction (n = 14. 61%) were common associated findings. Regarding the primary lesion, the majority was linitis plastica (n = 16) and poorly differentiated adenocarcinoma with or without signet-ring cell differentiation (n = 14).Conclusion: Intestinal metastasis: from gastric adenocarcinoma, especially of the linitis plastica type. most commonly showed target-like long segmental wall thickening with a characteristically thick inner enhancing layer on helical CT.
