鼻咽部淋巴瘤的CT诊断

CT Diagnosis of the Lymphoma of Nasopharynx

目的研究鼻咽部淋巴瘤的CT表现。资料与方法回顾性分析45例经病理证实的鼻咽部淋巴瘤影像表现。结果45例均表现为突入鼻咽腔内的均匀软组织密度肿块,30例可见口咽肿块,10例可见鼻腔内侵犯,30例伴有颈部淋巴结增大,仅1例见颅底骨质增生硬化。结论鼻咽部淋巴瘤表现为鼻咽腔内生长的均匀密度肿块影,很少侵犯周围深层组织。

Objective To describe CT appearances of nasopharyngeal lymphoma. Materials and Methods CT find- ings in 45 patients with lymphoma in nasopharynx proved by pathology were reviewed retrospectively. Results A homoge- neous isodense mass in nasopharynx was found in all patients,in which oropharynx was involved in 30 cases （66.7%） ,the nasal cavity was involved in 10 （22.2%）, lymphadenopathy was found in 30 （66.7 % ） cases. Skull base erosion was dis- played in only one case. Conclusion The lymphoma in the nasopharynx appeared as a homogeneous tumor in the nasopharynx without or with minimal invasion into deep structures.
