摘　　要：目的探讨鼻腔、鼻窦非霍奇金淋巴瘤(NHL)的CT特点,提高其诊断准确性。资料与方法回顾性分析11例经病理证实的鼻腔及鼻窦NHL的CT表现。结果 11例中原发鼻腔8例,鼻窦3例。8例鼻腔病灶中5例起源于鼻前庭或鼻腔前部;病灶肿块表现4例,浸润表现2例,混合表现5例,多数(9/11)密度相对均匀;位于鼻窦者骨质破坏明显且可膨胀性压迫骨质;位于鼻腔者骨质破坏不明显或较轻微;病灶易累及邻近结构。结论鼻腔、鼻窦NHL的CT表现有一定特征性,CT在该病的诊断中有重要意义。Purpose To explore the CT features of non-Hodgkin＇s lymphoma （NHL） in nasal cavity and paranasal sinuses, and to promote the diagnostic accuracy. Materials and Methods The CT images of 11 patients with NHL in nasal cavity and paranasal sinuses confirmed by pathology were retrospectively analyzed. Results Among 11 cases of NHL, 8 cases were primary nasal cavity NHL, and 3 cases were primary paranasal sinuses NHL. The lesions of 5/8 cases located in nasal cavity arose mainly from nasal vestibule or anterior part of nasal cavity; 4 cases showed mass effects, 2 cases were infiltrative and 5 cases were mixed. Most of them （9/11） were homogeneous. The cases with mass in paranasal sinuses had obvious bone destruction and expansively bone compression; and the lesions located in the nasal cavity showedunconspicuous or little bone destruction. The adjacent structures were always involved. Conclusion The NHL in the nasal cavity and paranasal sinuses has some characteristic features on CT images; CT scan plays importantrolein diagnosis of NHL.
