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。
Objective: To investigate the CT and MRI data of nasal and paranasal lymphoma and summarize the imaging features to provide help for clinical diagnosis. Methods: The CT and MRI images of nasal and paranasal sinus lymphoma confirmed by operation and biopsy in our hospital were retrospectively analyzed. According to the lesion site, extent of invasion, bone destruction and its density, signal characteristics, degree of enhancement, and adjacent tissues Statistical evaluation. Results: The NHL of NK / T cells and T cells were characterized by diffuse growth and widely existed in the respiratory area of the nasal cavity. The lesions of the middle and inferior turbinate generally changed in the mold, the local bone slightly eroded and the dashed line destroyed. Significant bone metastases, uneven density of lesions, tumor border ambiguity, the overall mixed signal; B cell NHL lesions originated in the front of the nasal cavity, adjacent to the surrounding tissue oppression, showed partial expansion of the growth of local bone with worms Erosion sample, the dash line change, often mild bony shift, the tumor boundary is relatively clear, lesion signal is more uniform, part of the tumor uniform enhancement. CONCLUSION: The imaging changes of nasal and paranasal sinus lymphoma are characteristic. The changes of imaging findings suggest pathological classification, which may be helpful for clinical diagnosis.
