| 目的 对比分析胃间质瘤（GST）与胃炎性纤维性息肉（IFP）CT征象。方法 回顾性分析经手术病理证实的80例GST患者和14例IFP患者的临床、病理及CT资料，比较其CT征象、年龄及CT值差异。结果 GST与IFP间，肿瘤最大径和平扫、动脉期、静脉期CT值、肿瘤形态、生长方式、囊变、周围淋巴结转移、肿瘤血管、强化方式、强化程度差异均有统计学意义（P均<0.05）。GST形态不规则，瘤体相对较大，平扫密度较高，以腔外生长为主，易坏死囊变及周围淋巴结转移，内部血管丰富，明显不均匀强化。二者间肿瘤边界、钙化、出血、溃疡、延迟期CT值及患者年龄差异均无统计学意义（P均>0.05）。结论 CT征象可作为鉴别诊断GST与IFP的影像学参考依据。 |

| Objective To compare CT signs of gastric stromal tumor (GST) and inflammatory fibroid polyp (IFP). Methods The clinical, pathological and CT data of 80 patients with GST and 14 patients with IFP confirmed by surgical operation and pathology were retrospectively analyzed. CT signs, patient's age and CT values were compared. Results There were statistically significant differences between GST and IFP in tumor size, plain CT value, CT value during arterial phase and venous phase, tumor morphology, growth pattern, cystic change, peripheral lymph nodes metastasis, tumor blood vessels, enhancement mode and degree of enhancement (all P<0.05). GST on CT was commonly irregular in shape, with relatively large size, and plain CT density was high, mainly extraluminal grew and tended to necrotic cystic change and peripheral lymph node metastasis, with rich internal blood vessels and obvious uneven enhancement. There was no statistically significant difference in tumor boundary, calcification, hemorrhage, ulcer, delayed CT value and age between the two tumors (all P>0.05). Conclusion CT signs can be used as references for differential diagnosis of GST and IFP. |
