恶性纤维组织细胞瘤的CT/MRI表现

CT and MRI Findings of Malignant Fibrous Histiocytoma

摘要: 目的:探讨恶性纤维组织细胞瘤(MFH)的CT/MRI影像学特点。方法:回顾性分析12例恶性纤维组织细胞瘤患者CT/MRI影像学资料,并评价肿瘤部位、大小、边缘、密度/信号、形态学特征、毗邻结构改变、增强表现与肿瘤局部与远处转移情况。结果:肿瘤边界大多数清晰。肿瘤密度/信号均匀性差。肿瘤毗邻结构受推挤居多。肿瘤不均匀强化。肿瘤形态呈分叶状或椭圆形。结论:CT/MRI影像学特点对临床鉴别诊断软组织恶性纤维组织细胞瘤有重要价值,是临床推荐应用的检查方法。

Abstract: objective: To approach the CT/MRI imaging signs of the malignant fibrous histiocytoma(MFH). Methods: 12 patients of MFH with CT/MRI imaging were retrospectively analyzed. The tumors of location, size, margins, density/signal, morphological characteristics, change of adjacent structure, enhance performance, local and distant metastasis of tumors were evaluated.Results The tumors have well-defined margins, poor uniformity of the density/signal, variable heterogeneous enhancement, lobulated or ellipse soft-tissue mass. Conclusion: The CT/MRI imaging findings have more characters for differential diagnosis in MFH,was a useful diagnosis instrument for clinical
