| 摘 要： | 目的探讨鼻腔NK/T细胞淋巴瘤的CT及MRI表现特征。材料和方法回顾性分析21例经病理证实的鼻腔NK/T细胞淋巴瘤患者的CT和MRI影像学资料及临床资料。结果本组21例中单侧7例,双侧14例,依据病变范围将本病分为局限型和弥漫型两种类型。局限型13例,主要位于鼻腔内,其中鼻腔前部11例,鼻腔后部2例;骨质改变不明显,浸润鼻旁或面部皮下组织9例,弥漫型8例,肿瘤范围广泛并向鼻腔周围结构浸润扩展,其中累及鼻旁窦7例,侵入眼眶1例、颞下窝2例,延伸至鼻咽、口咽部并累及咽旁间隙6例,骨质破坏7例,颈部淋巴结受累1例。CT显示肿瘤呈软组织密度充填鼻腔并沿鼻黏膜蔓延,增强后轻到中度不均匀强化。MRIT1WI肿瘤呈等信号,信号强度类似或稍低于肌肉;T2WI呈不均匀稍高信号,信号强度高于肌肉,但低于鼻黏膜,增强后轻到中度不均匀强化。结论鼻腔NK/T细胞型淋巴瘤影像学表现有一定特征,CT、MRI检查可提示诊断,有利于确定病变范围及临床分期。

| Abstract: | Purpose To characterize CT and MRI features of primary nasal cavity NK/T cell non-Hodgkin's lymphoma.Materials and Methods CT or/and MRI findings of 21 cases with nasal cavity NK/T cell lymphoma verified by pathologically were analyzed retrospectively.Results Of all 21 cases,7 were involved in unilateral nasal cavity,14 were involved in bilateral nasal cavity.Nasal cavity NK/T cell lymphoma was divided into localized type and diffuse type according to the range of lesion.A total of 13 cases were localized t... |
