摘要
目的探讨鼻及鼻咽部NK/T细胞淋巴瘤(NKTCL)的CT表现特点。方法回顾性分析28例经组织学证实的鼻及鼻咽部NKTCL的CT及临床资料。结果鼻腔病变为主者21例,其中14例鼻中隔受累,6例伴有鼻咽和(或)口咽受侵,2例软腭受侵。鼻腔病变者10例,鼻腔肿块呈铸型,肿块增强后密度同肌肉相仿;1例上腭受侵者及2例后鼻孔受累者病变密度不均可见气泡影。咽淋巴环为主者7例,5例显示增厚的咽壁管腔面毛糙、不光滑,1例显示表面气泡影。鼻腔病变为主者14例合并鼻旁窦窦腔透光度降低,6例鼻前庭皮肤受侵犯,12例显示骨质侵蚀破坏。28例中14例出现颈部淋巴结肿大。结论鼻及鼻咽部NKTCLCT表现具有一定的特征,有助于诊断。
Objective To investigate the CT features of natural killer cell/T cell lymphoma （NKTCL） in nasal cavity and nasopharynx. Methods CT features and clinical findings of 28 patients of NKTCL infiltrated into nasal cavity and nasopharynx confirmed histo-pathologically were analyzed retrospectively. Results Nasal cavity was mainly involved in 21 patients. Involvement of nasal septum was detected in 14 patients, nasopharynx and oropharynx in 6 and soft palate in 2 patients. Nasal cavity was filled with massive tumor of even CT density in 10 patients. In post contrast CT images, tumor showed isodensity to adjacent muscle. Uneven CT density was observed in 3 patients including 1 with palate involved and 2 with posterior nasal cavity. Waldeyer＇s ring was infiltrated in 7 patients, the surface of thickened wall of nasopharynx or oropharynx showed uneven in 5 and air-bubble was observed in 1 patient. Sites of extension outside the nasal cavity included paranasal sinuses （n= 14） and subcutaneous soft tissue of the face （n=6）. Bony destruction was demonstrated in 12 patients. Regional lymphadenopathy was also detected in 14 patients with NKTCL. Conclusion Some CT features may suggest the diagnosis of NKTCL in nasal cavity and nasopharynx.
