【摘要】：目的探討腸系膜間質(zhì)瘤的CT征象與惡性危險度相關(guān)性。方法回顧性分析經(jīng)手術(shù)及病理證實(shí)的27例腸系膜間質(zhì)瘤患者的CT表現(xiàn),將腫瘤的大小、形態(tài)、密度、生長方式、界限、壞死囊變、鈣化、強(qiáng)化方式與強(qiáng)化程度、遠(yuǎn)處轉(zhuǎn)移等征象與腫瘤惡性危險度分級進(jìn)行對照分析。結(jié)果 27例腫瘤直徑3.0~20.5 cm,平均9.6 cm;類圓形17例,不規(guī)則形10例;腫瘤與周圍組織界限清楚14例,界限不清13例;腫瘤密度均勻11例,不均勻16例;低密度12例,等密度13例,高密度2例;腫瘤壞死囊變13例;肝臟轉(zhuǎn)移3例,盆腔和腸系膜淋巴結(jié)轉(zhuǎn)移9例,伴出血7例,少量腹腔積液12例。增強(qiáng)掃描均勻強(qiáng)化11例,不均勻強(qiáng)化16例;輕度強(qiáng)化7例,中度強(qiáng)化10例,明顯強(qiáng)化10例,瘤內(nèi)伴迂曲增粗異常血管8例。腫瘤高危險度8例,中危險度9例,低危險度7例,極低危險度3例。單變量分析結(jié)果顯示:腫瘤大小、形態(tài)、生長方式、邊緣情況、強(qiáng)化方式、壞死囊變、遠(yuǎn)處轉(zhuǎn)移等差異有統(tǒng)計學(xué)意義(P0.05)。結(jié)論腸系膜間質(zhì)瘤CT表現(xiàn)具有一定的特征性,腫瘤大小可用于預(yù)測腫瘤危險程度,對治療和隨訪有指導(dǎo)意義。
[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.
