目的探讨原发于鼻腔的非霍奇金淋巴瘤的CT表现特点,探讨CT对该病的诊断价值。方法回顾性分析经病理证实的原发于鼻腔的非霍奇金淋巴瘤患者12例,分析其CT表现,并进行鉴别诊断。结果 12例鼻腔淋巴瘤中,9例为NK/T细胞淋巴瘤,2例为弥漫性大B细胞淋巴瘤,1例为T细胞淋巴瘤。所有病例均为位于一侧鼻腔内的软组织影,位于鼻腔前部或占据整个鼻腔,2例伴有鼻前庭皮肤受累;8例伴有副鼻窦受累;2例伴有同侧眼眶受侵;2例骨质破坏;1例颈部淋巴结受累。CT显示肿瘤呈软组织密度,增强后轻到中度均匀强化。结论原发于鼻腔的非霍奇金淋巴瘤CT表现有一定特征,常规CT检查可提示诊断,最终病理分型仍需病理及免疫组化明确。
Objective To investigate the CT features of primary non-Hodgkin lymphoma in the nasal cavity and to explore the diagnostic value of CT in the disease. Methods Retrospective analysis of 12 cases of pathologically confirmed non-Hodgkin’s lymphoma in the nasal cavity. The CT findings were analyzed and the differential diagnosis was performed. Results Among the 12 cases of nasal lymphoma, 9 were NK / T cell lymphoma, 2 were diffuse large B cell lymphoma and 1 were T cell lymphoma. All cases were located in the side of the nasal soft tissue shadow, located in the front of the nasal cavity or occupy the entire nasal cavity, 2 cases associated with nasal vestibular skin involvement; 8 cases associated with paranasal sinus involvement; 2 cases with ipsilateral orbital invasion; 2 Cases of bone destruction; 1 case of cervical lymph node involvement. CT showed soft tissue density of the tumor, enhanced mild to moderate and uniform enhancement. Conclusions CT findings of primary non-Hodgkin’s lymphoma in the nasal cavity have certain characteristics. Conventional CT examination can be a diagnosis, the final pathological classification still need clear pathology and immunohistochemistry.
