【摘要】 目的研究舌鳞癌和舌淋巴瘤的MRI影像学征象,探讨MRI在舌鳞癌与舌淋巴瘤的诊断与鉴别诊断中的应用。方法回顾性分析经手术病理证实为舌鳞癌和舌淋巴瘤共39例患者术前MR影像资料和临床资料。结果舌鳞癌表现为好发于舌体舌周缘的肿块,局部舌黏膜破坏;舌弥漫大B细胞淋巴瘤表现为好发于舌根部的黏膜下信号均匀的肿块,局部黏膜多完整;舌NK/T细胞淋巴瘤表现为舌弥漫性肿大,信号不均,边界模糊。结论舌部肿瘤检查首选MRI;舌淋巴瘤和舌鳞癌的MRI征象及好发部位有区别,所以MRI不仅可以诊断舌肿瘤,还能对舌鳞癌及舌淋巴瘤的鉴别诊断提供非常有价值的影像信息。更多还原

【Abstract】 Objective To study the MR imaging characteristics of lingual squamous cell carcinoma and lingual Lymphoma,and to differentiate these lingual tumors. Methods The MRI and clinical data of 39 patients with lingual squamous cell carcinoma and lingual Lymphoma were retrospectively analyzed. Results Lingual squamous cell carcinoma was shown as a mass at the rim of the body of the tongue,with disrupted mucous membranes. MRI showed good performance with a homogeneous signal mass displaying primary diffuse large B-cell lymphoma at the base of the tongue,with the mucous membranes intact. Lingual NK / T-cell lymphoma was shown as a diffuse heterogeneous swelling of the tongue. Conclusion MRI should be the first choice in the diagnosis of lingual tumors. MRI could be used as a good method for differentiating lingual squamous cell carcinoma and lingual Lymphoma with different MR characteristics and different primary sites.更多还原
