目的探讨鼻腔淋巴瘤CT影像学表现及鉴别诊断,提高对该疾病的认识。方法对12例确诊鼻腔淋巴瘤的患者进行回顾性分析,统计原发肿瘤的部位及侵犯范围,总结肿瘤CT影像学特征。结果 CT显示,7例位于单侧鼻腔,5例位于双侧鼻腔,并有1例向后生长至后鼻孔。12例病例均未见钙化。肿块增强后呈轻度—中度均匀或不均匀强化,略低于正常肌肉强化,与周围软组织分界不清。1例肿块侵犯右眼眶,2例有颈部淋巴结肿大,9例伴有阻塞性副鼻窦炎,1例伴有病变侧乳突炎。11例肿块周围骨质破坏,以鼻甲破坏最为常见,其次为筛骨纸板、眼眶底壁、副鼻窦壁。病理检查示,NK/T细胞淋巴瘤8例,外周T细胞淋巴瘤4例。结论鼻腔淋巴瘤CT表现具有一定的特征性,结合临床病史,一定程度上可提示本病,为临床治疗提供依据。 Objective To investigate the CT imaging findings and differential diagnosis of nasal lymphoma and to raise awareness of the disease. Methods The clinical data of 12 patients with confirmed nasal lymphoma were analyzed retrospectively. The location of the primary tumor and the extent of the invasion were analyzed. The CT features of the tumor were summarized. Results CT showed that 7 cases were located in the unilateral nasal cavity, 5 cases were located in the bilateral nasal cavity, and 1 case of backward growth to the posterior nostril. No cases of calcification in 12 cases. After the enhancement was mild - moderate or uneven enhancement, slightly lower than the normal muscle enhancement, with the surrounding soft tissue demarcation. One of the masses invaded the right orbit, two had cervical lymph nodes, nine had obstructive paranasal sinusitis and one had lateral mastoiditis. 11 cases of bone around the destruction of the destruction of the turbinate is the most common, followed by the ethmoid cardboard, orbital floor, paranasal sinus wall. Pathological examination showed 8 cases of NK / T cell lymphoma and 4 cases of peripheral T cell lymphoma. Conclusion CT findings of nasal lymphoma have certain characteristics, combined with clinical history, to a certain extent, the disease can be prompted for clinical treatment to provide the basis.
