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 investigate the imaging findings of ligament-like fibroids. Methods: The pathological, clinical and radiographic findings of 4 cases with pathologically confirmed ligament-like fibroma were analyzed. Results: The incidence of 4 cases in this group were abdominal cavity, abdominal wall, chest wall and axillary and lower femur. Typical ligament-like fibroids show a more homogeneous single lesion, CT scan slightly higher than the adjacent soft tissue density or equal, in the MRI on the composition of the tumor can cause T2WI signal changes. After the enhancement of mild, uneven enhancement, the state is not clear. Can damage the surrounding bone and muscle. CONCLUSION: Ligamentous fibroma is an aggressive benign tumor. Imaging features are non-characteristic. Diagnostic diagnosis is still needed.
