摘要
目的评价MR在良性骨肿瘤及肿瘤样病变与恶性骨肿瘤周围水肿的价值。方法选取2015年1月~2019年12月我院接诊的64例骨肿瘤及肿瘤样病变患者为研究对象,依据病理结果分为良性组34例和恶性组30例,均进行MR检查。比较两组病灶周围的骨髓水肿及软组织水肿出现率、骨髓水肿及软组织水肿范围最大径与肿瘤范围最大径比值以及诊断灵敏性、特异性。结果两组骨髓水肿出现率比较,差异无统计学意义(P>0.05);良性组软组织水肿出现率低于恶性组,差异有统计学意义(P<0.05);良性组骨髓水肿最大径与肿瘤最大径比大于恶性组,差异有统计学意义(P<0.05);两组软组织水肿最大径与肿瘤最大径比、诊断灵敏性比较,差异无统计学意义(P>0.05);良性组诊断特异性低于恶性组,差异有统计学意义(P<0.05)。结论良恶性骨肿瘤和肿瘤样病变均会显示骨髓和软组织水肿,但良性骨肿瘤和肿瘤样病变周围骨髓水肿较恶性骨肿瘤常见,恶性骨肿瘤更多表现为周围软组织水肿,可为临床鉴别诊断良恶性骨肿瘤和肿瘤样病变提供给一定参考依据。
Objective To evaluate the value of MR in benign bone tumors and tumor-like lesions and edema around malignant bone tumors.Methods A total of 64 patients with bone tumors and tumor-like lesions admitted to our hospital from January 2015 to December 2019 were selected as the research objects.Based on the pathological results,they were divided into 34 cases in the benign group and 30 cases in the malignant group.All were examined by MR.The incidence of bone marrow edema and soft tissue edema around the two groups of lesions,the ratio of the maximum diameter of the bone marrow edema and soft tissue edema to the maximum diameter of the tumor,and the sensitivity and specificity of diagnosis were compared.Results There was no statistically significant difference in the incidence of bone marrow edema between the two groups(P>0.05);the incidence of soft tissue edema in the benign group was lower than that in the malignant group,the difference was statistically significant(P<0.05);The ratio of the maximum diameter of bone marrow edema to the maximum diameter of the tumor in the benign group was greater than that of the malignant group,the difference was statistically significant(P<0.05);the comparison of the ratio of the maximum diameter of soft tissue edema to the maximum diameter of the tumor and the sensitivity of diagnosis between the two groups was not statistically significant(P>0.05);the diagnostic specificity of the benign group was lower than that of the malignant group,the difference was statistically significant(P<0.05).Conclusion Both benign and malignant bone tumors and tumor-like lesions will show bone marrow and soft tissue edema,but benign bone tumors and tumor-like lesions surrounding bone marrow edema are more common than malignant bone tumors,and malignant bone tumors are more manifested as peripheral soft tissue edema,which can be a clinical differential diagnosis Benign and malignant bone tumors and tumor-like lesions provide a certain reference basis.
