摘　　要：目的探讨CT在嗅神经母细胞瘤诊断中的价值。方法回顾性分析14例经病理证实的嗅神经母细胞瘤的CT资料。结果原发部位多位于鼻腔上部和筛窦;CT可清晰显示肿瘤向周围侵犯的范围;表现为中等较均匀密度,注射造影剂后呈明显强化,多数强化不均匀。结论CT可确定肿瘤原发部位、侵犯范围以及与周围血管、神经的关系,为临床治疗方案的制定提供必要的参考依据。Objective To investigate the value of CT diagnosis of esthesioneuroblastoma. Methods 14 cases of pathologically comfirmed esthesioneuroblastoma were analysed retrospectively. Results （1）Primary site： superior nasal cavity and ethmoid sinus were the most common sites; （2）CT can show clearly the extent of infiltration of esthesioneuroblastoma; （3）Density： the tissue density on pre-contrast CT was equal to that of muscle and was relatively homogenous. Following intravenous contrast, significant enhancement was found and variable uniformity. Conclusion CT are helpful for evaluating the primary site, extent of tumor, and its relationship to vessels and nerves. It is provided more useful information for clinical planning.
