| 目的 分析鼻腔自然杀伤细胞(NK)/T细胞淋巴瘤的CT及磁共振成像(MRI)表现,探讨其影像学特征,以提高诊断的准确性。方法 回顾性分析16例经手术病理证实鼻腔NK/T细胞淋巴瘤的CT及MRI表现。16例患者中10例仅接受CT扫描,其中5例接受CT平扫及增强扫描,5例接受CT平扫；4例仅接受磁共振(MR)扫描,其中3例接受MR平扫及增强扫描,1例接受MR平扫；2例同时接受CT平扫及MR平扫及增强。结果 16例患者单侧肿瘤8例,双侧肿瘤8例。病灶局限性于鼻腔前中部6例,中后部3例,弥漫分布于整个鼻腔7例。16例NK/T细胞淋巴瘤中10例出现轻度骨质吸收,骨质改变轻微。肿瘤浸润鼻前庭、 鼻翼、 鼻背或邻近面部软组织11例。病灶与鼻中隔、鼻甲或鼻窦壁间存有小气泡11例。CT平扫肿瘤呈等或稍低密度, MRI表现为T1WI稍低信号,T2WI稍高信号,增强后均轻中度强化。结论 鼻腔NK/T细胞淋巴瘤CT及MRI表现具有一定特征,有助于该病的诊断。 |

| Objective To analyze the computed tomography (CT) and magnetic resonance imaging (MRI) manifestations of natural killer T-cell (NK/T cell) lymphoma in nasal cavity and to explore its radiological features,in order to improve the accuracy of diagnosis.Methods CT and MRI manifestations of 16 patients with pathologically proven NK/T cell lymphoma in nasal cavity were retrospectively analyzed.Ten patients were scanned with CT,among whom 5 underwent plain and contrast-enhanced scan,5 underwent only plain scan.Four patients were scanned with MR,among whom 3 underwent plain and contrast-enhanced scan,1 underwent only plain scan.Two patients were scanned with CT plain scan and MR plain and contrast-enhanced scan.Results Tumors in 8 cases were located in unilateral nasal cavity,while tumors in another 8 cases in bilateral nasal cavity.The foci were confined to the anterior central nasal cavity in 6 cases,posterior central nasal cavity in 3 cases and were diffused in 7cases.Ten cases had mild bony absorption,with slight bony change.Eleven cases had tumor infiltration to nasal vestibule,nosewing,nasal dorsum or the adjacent facial soft tissue.Eleven cases had small bubbles between the foci and nasal septum,turbinate or the sinus wall.The lesions showed low or iso-density on CT plain scan images.T1-weighted images showed that tumors had slightly lower signal intensity and T2-weighted images showed that tumors had slightly higher signal intensity.The lesions had slight-mild reinforcement after contrast enhancement.Conclusion CT and MRI findings of NK/T cell lymphoma in nasal cavity are relatively characteristic,which is helpful for its diagnosis. |
