摘要
目的:探讨MRI对侵袭性纤维瘤病术前评估的应用价值。方法:回顾分析11例侵袭性纤维瘤病的MRI表现及术中所见,并对4例大体病理标本进行组织大切片和特殊染色。结果:T1WI呈等信号5例,稍低信号6例,T2WI均呈稍高信号,内见星芒状、条索状低信号,增强后病灶明显强化。边界不清10例,边缘呈爪状生长;边缘清晰1例,可见假包膜。术中见7例与邻近血管粘连,4例累及邻近神经。结论:侵袭性纤维瘤病的MRI表现具有一定特征性,MRI可反映侵袭性纤维瘤病的组织学特点,并能显示肿瘤与邻近血管的关系,可作为诊断侵袭性纤维瘤病的首选方法。
Objective: To investigate the value of MRI in the assessment of aggressive fibromatosis before operation. Methods: MR appearance of 11 histologically proven aggressive fibromatosis were retrospectively analyzed and compared with manifestations in operation and pathology. Large tissue section and special staining were performed in 4 specimens. Results: Tumors showed isointensity in 5 cases and hypointensity in 6 eases on T1WI, and moderate hyperintensity in all cases on T2WI with low signal in some region . T1WI after intravenous contrast administration in all cases showed strong enhancemant, except for the areas of low signal on T2WI. Margins were ill defined in 10 cases, well defined in 1 case. During operation, tumors were seen to be adhered to vessles in 7 case and nerve in 4 cases. Conclusion:MRI can demonstrate the histiologie features of aggressive fibromatosis and involvement of vessles, and can be ehoosed as the primary method for diagnosis.
