| 目的 探讨CEUS鉴别诊断胃间质瘤与Bormann Ⅱ型胃癌的价值。方法 回顾性分析17例胃间质瘤和12例Bormann Ⅱ型胃癌患者术前二维超声和CEUS图像，评估CEUS鉴别诊断胃间质瘤与Bormann Ⅱ型胃癌的效能。结果 胃间质瘤多表现为局部胃壁层次结构清晰，肿物位于固有肌层（13/17，76.47%），CEUS呈向心性增强（15/17，88.24%），多数肿物表面可见光滑、连续完整的环状增强，为“蛋壳征”（14/15，93.33%）。Bormann Ⅱ型胃癌多表现为局部胃壁层次结构不清晰（10/12，83.33%），CEUS呈弥漫性增强（9/12，75.00%），12例Bormann Ⅱ型胃癌均未见“蛋壳征”。胃间质瘤与Bormann Ⅱ型胃癌在局部胃壁层次结构、强化顺序及“蛋壳征”方面差异有统计学意义（P均<0.05）。Bormann Ⅱ型胃癌时间强度曲线的下降斜率（DS）大于胃间质瘤（0.60 dB/s vs 0.32 dB/s，P<0.05）。局部胃壁层次结构是否清晰、病灶强化顺序以及“蛋壳征”鉴别诊断胃间质瘤与Bormann Ⅱ型胃癌的准率度分别为79.31%（23/29）、82.76%（24/29）、96.30%（26/27）。结论 CEUS鉴别胃间质瘤与Bormann Ⅱ型胃癌有一定的临床价值。 |

| Objective To explore the value of CEUS in differential diagnosis of gastric stromal tumor and Bormann type Ⅱ gastric cancer.Methods The data of 2D-ultrasonography and CEUS of 17 cases of gastric stromal tumors and 12 cases of Bormann type Ⅱ gastric cancers was analyzed retrospectivly to assess the efficacy of CEUS in differential diagnosis of gastric stromal tumor and Bormann type Ⅱ gastric cancer.Results Gastric stromal tumors showed that the layers of local gastric were clear, tumor located in the muscularis propria (13/17, 76.47%). CEUS showed centripetal progression of enhancement in gastric stromal tumors (15/17, 88.24%). Most of the gastric stromal tumors showed a smooth and continuous ring-like enhancement, called "eggshell" sign (14/15, 93.33%). However, gastric cancers often showed the layers were not clear (10/12, 83.33%). And diffuse enhancement (9/12, 75.00%) were often shown in CEUS. All of the 12 cases of gastric cancer had no "eggshell" signs. Descending slope (DS) of gastric cancer was greater than that of gastric stromal tumor (0.60 dB/s vs.0.32 dB/s, P<0.05). The features of layers of local gastric wall, the order of enhancement, "eggshell" sign were statistically significant between gastric stromal tumors and Bormann type Ⅱ gastric cancers (P<0.05). The accuracies of layers of local gastric wall, the order of enhancement and "eggshell" sign to differential diagnose gastric stromal tumor and Bormann type Ⅱ gastric cancer were 79.31% (23/29), 82.76% (24/29), 96.30% (26/27) respectively.Conclusion CEUS has certain efficacy in differential diagnosis of gastric stromal tumor and Bormann type Ⅱ gastric cancer. |
