目的 :探讨鼻腔鼻窦非霍奇金淋巴瘤 ( NHL)的 CT影像学特征。方法 :对 9例经病检确诊为鼻腔鼻窦 NHL患者的 CT片进行回顾性分析。结果 :原发于鼻腔鼻窦的 NHL在临床上有着典型的恶性特征 ,但在 CT影像上所表现的骨质破坏 ,类似于良性病变的骨改建、骨膨胀性改变 ,而非其他恶性肿瘤那样表现为侵入性骨质破坏 ;其在鼻腔内形成均匀软组织密度影 ,常累及下鼻道、下鼻甲 ;并伴有鼻中隔前份粘膜对称性增厚。结论 :原发于鼻腔鼻窦的 NHL在 CT影像上有其自身特征 ,可为本病的诊断提供参考依据。
Objective: To investigate CT features of nasal sinus non-Hodgkin’s lymphoma (NHL). Methods: Nine patients with nasal sinus diseases diagnosed by pathology were retrospectively analyzed. Results: The NHL in the nasal cavity and paranasal sinuses had typical malignant features in clinical practice. However, the CT images showed bone destruction similar to benign bone remodeling and bone expansion, but not to other malignant tumors For invasive bone destruction; its formation of uniform soft tissue density in the nasal cavity, often involving the lower nasal, inferior turbinate; and accompanied by nasal septum mucosal symmetry before thickening. Conclusion: NHL originating in nasal sinuses has its own characteristics in CT images, which can provide reference for the diagnosis of this disease.
