目的:探讨恶性纤维组织细胞瘤( MFH)在MR中的成像特征。方法回顾性分析经病理证实的39例MFH患者的MR图像特点。结果39例恶性纤维组织细胞瘤中,33例肿瘤瘤体实质部分T1WI表现为低、中等信号,T2 WI表现为以高信号为著的混杂信号。瘤体内出血10例,瘤体内坏死或黏液变性14例,均表现为双高信号。瘤体周围出现水肿23例,瘤体周围局部出现肌肉、血管神经束压迫征象25例,出现明显骨质受累21例。39例强化扫描瘤体周边强化明显,瘤体近中心区强化不显著或无强化表现。结论 MR可清楚显示MFH肿瘤范围、组织成分及其与周围结构的关系,是MFH的首选检查方法。
目的:探討噁性纖維組織細胞瘤( MFH)在MR中的成像特徵。方法迴顧性分析經病理證實的39例MFH患者的MR圖像特點。結果39例噁性纖維組織細胞瘤中,33例腫瘤瘤體實質部分T1WI錶現為低、中等信號,T2 WI錶現為以高信號為著的混雜信號。瘤體內齣血10例,瘤體內壞死或黏液變性14例,均錶現為雙高信號。瘤體週圍齣現水腫23例,瘤體週圍跼部齣現肌肉、血管神經束壓迫徵象25例,齣現明顯骨質受纍21例。39例彊化掃描瘤體週邊彊化明顯,瘤體近中心區彊化不顯著或無彊化錶現。結論 MR可清楚顯示MFH腫瘤範圍、組織成分及其與週圍結構的關繫,是MFH的首選檢查方法。

Objective To investigate the MR imaging features of malignant fibrous histiocytoma ( MFH) .Methods Analysis MR images of 39 cases with MFH which confirmed by pathological .Results In the 39 cases of malignant fibrous his-tiocytoma, 33 cases of cancer tumor T1WI showed a substantial part of the low , iso-signal, T2WI showed high signal is mixed with heterogeneous signal .Tumor hemorrhage in 10 cases, intratumoral necrosis or mucoid degeneration in 14 cases, showed double high signal.Swelling around the tumor occurs in 23 cases, partial muscle around the tumor , signs of compression of neurovascular bundles in 25 cases, 21 cases of apparent bone involvement .39 cases of peripheral enhancement significantly enhanced scan of the tumor , the tumor near the central area not significantly enhanced or without enhancement .Conclusion MR can clearly show the range of tumor , ingredients and its relationship with surrounding structures , MR was the first choice for diagnose the MFH .
