摘要: 目的：探讨鼻腔鼻窦淋巴瘤CT及MRI资料，总结影像学特点，为临床诊断提供帮助。方法：回顾性分析我院经手术及活检病理证实的鼻腔鼻窦淋巴瘤CT、MRI的影像资料，针对病灶部位、侵及范围、骨质破坏以及其密度、信号特点、强化程度、邻近组织情况进行统计评估。结果：NK/T细胞、T细胞NHL以弥漫性生长为特点，广泛存在于鼻腔呼吸区，常累及中、下鼻甲整体呈铸型改变，局部骨质轻微虫蚀样、虚线样破坏，且无明显的骨性移位，病灶密度不均，肿瘤边界模糊，整体呈混杂信号；B细胞NHL病灶起源于鼻腔前部，对周围邻近组织有压迫表现，局部呈膨胀性生长，局部骨质有虫蚀样、虚线样改变，常有轻度骨性移位，肿瘤边界相对清楚，病灶信号较均匀，部分瘤体均匀强化。结论：鼻腔鼻窦淋巴瘤影像学改变具有特征性，影像学改变提示病理分型，可为临床诊断提供帮助。Abstract: Objective: Analysis of nasal lymphoma CT and MRI data, summarize imaging characteristics,provide help for clinical diagnosis.Method: Retrospectively analyzed the image manifestations of 32 cases of nasal lymphoma diagnosed by surgery and pathology.Lesion locations, tumor extension, bone destruction and its density, signal characteristics, enhancement degree, the situation of adjacent tissues were evaluated.Result: NK/T cells, T cell NHL have the characteristics:the lesions to diffuse growth, widely existed in nasal breathing zone, often involving middle and inferior turbinate, local bone slightly damaged, and no obvious bony shift. Tumor of uneven density, fuzzy boundaries, mixed signalse. The characteristics of B cell NHL:the lesion originated in the front of the nasal cavity, on the surrounding adjacent tissue compression performance, local feature is swelling growth and bone have insect damage sample sample, the dotted line change, very mild osseous shift, the tumor boundary is relatively clear, lesions density is uniform, and part of the uniform tumors had signal.Conclusion: Nasal lymphoma imaging changes have its characteristics. Image change prompts the pathological classification, providing help for clinical diagnosis.
