【摘要】：目的探讨肠系膜间质瘤的CT征象与恶性危险度相关性。方法回顾性分析经手术及病理证实的27例肠系膜间质瘤患者的CT表现,将肿瘤的大小、形态、密度、生长方式、界限、坏死囊变、钙化、强化方式与强化程度、远处转移等征象与肿瘤恶性危险度分级进行对照分析。结果 27例肿瘤直径3.0~20.5 cm,平均9.6 cm;类圆形17例,不规则形10例;肿瘤与周围组织界限清楚14例,界限不清13例;肿瘤密度均匀11例,不均匀16例;低密度12例,等密度13例,高密度2例;肿瘤坏死囊变13例;肝脏转移3例,盆腔和肠系膜淋巴结转移9例,伴出血7例,少量腹腔积液12例。增强扫描均匀强化11例,不均匀强化16例;轻度强化7例,中度强化10例,明显强化10例,瘤内伴迂曲增粗异常血管8例。肿瘤高危险度8例,中危险度9例,低危险度7例,极低危险度3例。单变量分析结果显示:肿瘤大小、形态、生长方式、边缘情况、强化方式、坏死囊变、远处转移等差异有统计学意义(P0.05)。结论肠系膜间质瘤CT表现具有一定的特征性,肿瘤大小可用于预测肿瘤危险程度,对治疗和随访有指导意义。
[Abstract]:Objective to investigate the correlation between CT signs and malignant risk of mesenteric stromal tumors (mesenteric stromal tumors). Methods the CT findings of 27 cases of mesenteric stromal tumors confirmed by operation and pathology were retrospectively analyzed. The size, shape, density, growth pattern, boundary, necrotic cystic change, calcification, enhancement mode and degree of enhancement of the tumor were analyzed. The distant metastasis isomorphism was compared with the grade of malignant risk. Results in 27 cases, the mean diameter of tumor was 3.020. 5 cm, 17 cases were round and 10 cases were irregular, the boundary between tumor and surrounding tissue was clear in 14 cases, the boundary was not clear in 13 cases, the density of tumor was homogeneous in 11 cases and uneven in 16 cases. There were 12 cases of low density, 13 cases of isodensity, 2 cases of high density, 13 cases of necrotic cysts, 3 cases of liver metastasis, 9 cases of pelvic and mesenteric lymph node metastasis, 7 cases of hemorrhage and 12 cases of peritoneal effusion. There were 11 cases of homogeneous enhancement, 16 cases of uneven enhancement, 7 cases of mild enhancement, 10 cases of moderate enhancement and 10 cases of obvious enhancement. There were 8 cases of high risk, 9 cases of middle risk, 7 cases of low risk and 3 cases of very low risk. The results of univariate analysis showed that there were significant differences in tumor size, morphology, growth pattern, edge condition, enhancement mode, necrotic cystic change, distant metastasis and so on (P0.05). Conclusion the CT features of mesenteric stromal tumors are characteristic and the size of mesenteric stromal tumors can be used to predict the degree of tumor risk. It is helpful for the treatment and follow-up of mesenteric stromal tumors.
