摘　　要：目的探讨韧带样瘤的MRI表现,提高MRI对该病的诊断符水平。方法回顾分析6例经手术病理证实的韧带样瘤的MRI表现。结果 6例病理证实的病例中,浸润性生长3例,膨胀性生长3例,MRI信号混杂信号,T1WI以等信号为主,接近邻近肌肉信号,T2WI以略高信号为主,压脂序列呈高信号,所有病例中可见片状或索条状低信号,增强扫描肿瘤不均匀强化。结论 MRI检查显示韧带样瘤的形态、信号、强化方式等方面有一定的特征性,具有鉴别诊断价值。Objective To explore the clinical and MR imaging features of desmoid-type fibromatosis in order to achieve more information about the disease and to improve the diagnosis. Methods The clinical and MRI imaging data of 6 patients＇ desmoid-type fibromatosis confirmed by pathology were retrospectively analyzed. Results 6 cases of histologically confirmed cases, invasive growth in 3 cases, expansive growth in 3 cases, on T1 weighted images, 4 tumors showed homogeneous signal isointensity relative to muscle, or heterogeneous signal intensity; on T2-weighted images showed hyper intensity. In all lesions, acord-like or patch-like low signal could befound. All lesions showed heterogeneous enhancement. Conclusion MRI examination revealed a desmoid tumor morphology, signal, enhanced mode has certain characteristics, has the value of differential diagnosis.
