【摘要】：目的分析嗅神經(jīng)母細(xì)胞瘤的MRI、MSCT征象,探討MRI和MSCT診斷該病的臨床價(jià)值。方法收集17例經(jīng)手術(shù)、穿刺、病理證實(shí)的嗅神經(jīng)母細(xì)胞瘤的臨床及影像學(xué)資料,回顧性分析其MRI、MSCT表現(xiàn)。結(jié)果 14例腫瘤位于單側(cè)鼻腔,其中左側(cè)6例,右側(cè)8例,3例位于雙側(cè)鼻腔。A期2例,B期6例,C期9例,D期0例。MRI平掃表現(xiàn)為不規(guī)則形腫塊,T_1WI呈等、低信號(hào),T_2WI呈高、稍高信號(hào);CT平掃表現(xiàn)為等、低混雜密度腫塊,1例見(jiàn)條狀、斑片狀鈣化灶;增強(qiáng)掃描呈輕度至明顯強(qiáng)化。7例復(fù)發(fā)。結(jié)論嗅神經(jīng)母細(xì)胞瘤有其好發(fā)部位,MRI及MSCT表現(xiàn)出一定的影像特征且能明確腫瘤分期,對(duì)臨床治療提供影像依據(jù)。
[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.
