【摘要】：目的分析嗅神经母细胞瘤的MRI、MSCT征象,探讨MRI和MSCT诊断该病的临床价值。方法收集17例经手术、穿刺、病理证实的嗅神经母细胞瘤的临床及影像学资料,回顾性分析其MRI、MSCT表现。结果 14例肿瘤位于单侧鼻腔,其中左侧6例,右侧8例,3例位于双侧鼻腔。A期2例,B期6例,C期9例,D期0例。MRI平扫表现为不规则形肿块,T_1WI呈等、低信号,T_2WI呈高、稍高信号;CT平扫表现为等、低混杂密度肿块,1例见条状、斑片状钙化灶;增强扫描呈轻度至明显强化。7例复发。结论嗅神经母细胞瘤有其好发部位,MRI及MSCT表现出一定的影像特征且能明确肿瘤分期,对临床治疗提供影像依据。
[Abstract]:Objective to analyze the MSCT features of olfactory neuroblastoma and to explore the clinical value of MRI and MSCT in diagnosis of olfactory neuroblastoma. Methods the clinical and imaging data of 17 cases of olfactory neuroblastoma proved by operation, puncture and pathology were analyzed retrospectively. Results the tumors were located in unilateral nasal cavity in 14 cases, of which 6 cases were left, 3 cases were located in bilateral nasal cavity, 2 cases were in stage A, 2 cases were in stage B, 6 cases were in stage C, 9 cases were in stage D. MRI plain scan showed that irregular tumor presented as T _ 1WI, and low signal intensity was high on T _ 2WI. The findings of CT plain scan with slightly higher signal intensity were isotropic, low mixed density mass (1 case) with stripe and patchy calcification, enhanced scan (7 cases) with mild to obvious enhancement (7 cases). Conclusion olfactory neuroblastoma has some imaging features on MRI and MSCT, and it can be used to determine tumor staging, which provides imaging basis for clinical treatment of olfactory neuroblastoma.
