目的:探讨鼻腔鼻窦非何杰金淋巴瘤(NHL)的CT特征。方法:回顾性分析12例经病理证实的鼻腔鼻窦NHL患者的CT影像和临床资料。结果:CT表现:(1)鼻腔NHL 9例,主要起源于鼻前庭或鼻腔前部;鼻窦NHL 3例,2例起源于上颌窦,1例同时起源于上颌窦和蝶窦;(2)病变形态可为浸润型5例,肿块型3例,混合型4例;(3)骨质破坏4例,轻微局限,以虫蚀样、虚线状骨质吸收为主;(4)多累及邻近结构,包括鼻翼、鼻咽及上颌窦后脂肪间隙等。结论:鼻腔鼻窦NHL在CT影像上有一定自身特征,CT扫描能提示诊断。
Objective: To investigate CT features of nasal sinus non-Hodgkin’s lymphoma (NHL). Methods: CT images and clinical data of 12 patients with pathologically confirmed nasal sinus NHL were retrospectively analyzed. Results: CT showed: (1) nasal NHL in 9 cases, mainly originated from nasal vestibule or nasal cavity; 3 cases of nasal sinus NHL, 2 cases originated from maxillary sinus, 1 case originated from maxillary sinus and sphenoid sinus; (2) There were 5 infiltration types, 3 mass type and 4 mixed type. (3) There were 4 cases of bone destruction with slight limitation, which were mainly worm-eaten and dotted bone absorption. (4) Involvement of adjacent structures , Including the nose, nasopharynx and maxillary sinus fat gap and so on. Conclusion: Nasal sinus NHL has its own characteristics in CT images, CT scan can prompt diagnosis.
