鼻腔非霍奇金淋巴瘤的CT诊断

CT features of non-Hodgkin's lymphoma(NHL)in nasal cavity

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 CT features of non-Hodgkin's lymphoma(NHL)in nasal cavity and assess the CT diagnostic value.METHODS 12 cases of primary NHL confirmed by pathology located in nasal cavity were retrospectively analyzed.RESULTS Of the12 cases of NHL,9cases were NK/T cell NHL,2were giant B cell NHL.1was T cell NHL.All cases were located in one nasal cavity unilaterally,either located in the anterior portion or fulfilling the whole nasal cavity.2were involved in paranasal or facial subcutaneous tissue,8cases among them involved the paranasal sinuses,2involved orbital invasion,2showed bone mass destruction,1involved neck lymph node.CT findings showed that soft tissue density tumor filled the nasal cavity,enhanced CT showed mild to moderate homogeneous enhancement.CONCLUSIONS There are some specific imaging featuresof the primary NHL in nasal cavities.The conventional CT examination can supply some diagnostic indications,but the definitive pathological typing still relies on pathology and immunohistochemical methods.
