摘　　要：目的:探讨原发鼻腔NK/T细胞淋巴瘤的CT表现特点,提高诊断水平。方法:搜集8例经病理证实的原发鼻腔NK/T细胞淋巴瘤,术前均行CT检查,分析其CT表现。结果:8例中双侧2例,单侧6例;3例肿块弥漫生长呈"铸型"改变,5例呈局限性肿块,其中3例位于鼻腔前庭部,2例位于后鼻孔;4例病变累及鼻翼、鼻背部及面颊部,2例肿块累及上颌窦,5例出现副鼻窦炎,2例有骨质破坏;1例出现颈部及颌下淋巴结肿大;CT平扫肿块呈较均匀的软组织密度,增强呈轻到中度强化。结论:原发鼻腔NK/T细胞淋巴瘤好发于一侧或双侧鼻腔前下部,呈局限性或弥漫性软组织肿块,往往累及鼻背、鼻翼及颌面部软组织,常伴有中线结构的骨质破坏,CT表现有一定的特征性,有助于病变的诊断。Objective：To investigate the CT features of natural killer cell/T-cell lymphoma in nasal cavity. Methods： Eight patients with natural killer ceil/T-cell lymphoma in nasal cavity proved by pathology had been examined by CT scan- ning,and CT images were analyzed retrospectively. Results：Of the 8 cases,2 cases were bilateral and 6 unilateral. Three ca- ses had the mass with diffuse growth presenting a ＂cast＂ change,and 5 cases showed the limitations of mass,of which three cases in the nasalvestibule,two cases in the nostrils. There were 4 cases of lesions involving the nose, dorsum of the nose and cheek,two cases of tumor involving the maxillary sinus, five cases showed sinusitis, 2 cases showed hone destruction; one case showed neck and submandibular lymph nodes. On plain CT scan lesions showed uniform soft tissue density, en- hanced lesions showed mild to moderate enhancement. Conclusion：Primary nasal NK/T cell lymphomas occur mostly in the front lower part of unilateral or bilateral nasal cavity,the lesions present as localized or diffuse soft tissue masss, often in- volve the nasal dorsum, alar and maxillofacial soft tissue,often accompanied by bone destruction of the midline structures. The CT findings have certain characteristics,which are helpful to the diagnosis of lesions.
