摘要
目的:探讨韧带样纤维瘤的影像学表现。方法:结合文献分析4例经术后病理证实的韧带样纤维瘤的病理、临床及影像学表现。结果:本组4例发病部位分别为腹腔、腹壁、胸壁及腋窝和股骨下段。典型的韧带样纤维瘤表现为较均质的单发病灶,CT平扫比相邻软组织密度稍高或相等,在MRI上可因肿瘤内成分不同而引起T2WI信号的变化。增强后有轻度、不均匀强化,境界不清晰。可破坏周围骨质及肌肉。结论:韧带样纤维瘤是一种具有侵袭性的良性肿瘤,影像学表现无特征性,确诊仍需要病理诊断。
Objective： To explore the imaging feature of desmoplastic fibromas. Method： To evaluate the pathological origination, clinical presentation and imaging presentation of desmoid tumor in four cases with review of the literature. Result： In the four cases, the lesions has different location. One is in abdominal wall, one is in chest wall and armpit, one is in the underneath of the femur and one is in abdomen. CT and MRI scan demonstrates the desmoid tumor originating from muscle with homogeneous formation. The lesion manifests lower attenuation lump contrasted to the adjacent soft tissue in CT scan and the different components of which lead to various signal in T2WI. After intraveinous contrast material administration, the lesion which has no clear margin always demonstrates inhomogeneous, slight enhancement. Conclusion： Desmoid tumor is an aggressive benign tumor. Because imaging findings have no characteristic, its diagnosis depends on pathological examination.
