【摘要】 目的 分析深部纤维瘤病的影像学表现,提高对本病的认识。方法 回顾性分析21例（男7例,女14例）深部纤维瘤病患者的临床特征及24个病灶的CT、MRI表现。结果 21例平均年龄31.8岁,其中12例（57%）<30岁,病程在1年以内者17例（81%）。24个病灶中腹内纤维瘤病2个（8.3%）,腹壁纤维瘤病病灶5个（20.8%）,腹壁外纤维瘤病病灶17个（70.9%）。深部纤维瘤病CT平扫呈稍低或等密度,强化形式变化较多。MRI T₁WI信号与肌肉相似或稍高、稍低,较均匀,T₂WI呈高信号但常不均匀,注射造影剂后肿块不均匀明显强化。病灶可呈大片低信号中串珠状多结节信号增高。肿块可压迫或侵蚀邻近骨质。结论 结合临床特点,CT和MRI能够对深部纤维瘤病作出正确的术前诊断。更多还原

【Abstract】 Objective To analyze CT and MRI findings of deep fibromatosis in order to improve the knowledge of it.Methods CT and MRI manifestations and clinical features of 21 cases（7 men and 14 women,24 lesions） with deep fibromatosis were analyzed.Results There were 12 cases（57%） younger than 30 years in age（mean age 31.8 years）.The courses of disease in 17（81%）cases were less then one year.There were 2 intra-abdominal fibromatosis,5 adominal fibromatosis and 17 extra-acbdominal fibromatosis.The lesions showed isodense or slightly hypodense on plane CT and different patterns of enhancement after contrast-enhanced.On MRI,the lesions showed homogeneous isointensity,slightly hyper-or hypo-intensity on T₁WI and inhomogeneous high signal intensity on T₂WI.Tumors were markedly but inhomogeneous enhanced post-contrast.Tumors in 2 cases showed multi-center high signal intensity among signal avoid regions.Bone around tumors could be pressed or destroyed.Conclusion In combination with clinical features,CT and MRI can make a correct diagnosis for deep fibromatosis before operation.更多还原
