摘　　要：目的评价影像学检查在随访嗅神经母细胞瘤的价值。方法分析5例嗅神经母细胞瘤随访过程中的CT、MRI表现。结果2例病人的存活时间超过5年。2例就诊时病变局限于鼻腔，在随访过程中，1例表现为右侧眼眶区硬膜外软组织肿块，同时左侧鼻腔内亦可见软组织肿块影，CT、MRI显示病变强化均匀，1个月后左侧鼻腔病变显著增大，且破坏了邻近硬腭。另1例病变则呈浸润性生长，CT显示颅底骨质广泛破坏，翼腭窝、颈动脉管、圆孔、卵圆孔均受累。MRI显示病变侵及颅内海绵窦、颈内动脉以及鞍区结构。另3例就诊时已为T4期，病变以鼻腔顶壁、筛窦为中心，侵犯颅内海绵窦以及鞍区结构，颅底骨质破坏。结论CT／MRI可清晰地显示病变的侵袭范围，对评价病变的生物学生长行为提供了客观依据。Objective To investigate the value of CT and MRI in following-up olfactory neuroblastoma. Methods 5 cases with olfactory neuroblastomas were followed-up with CT and MR imaging for several years（the longest, 5 years）, the imaging features were analysed. Results Two patients survived over 5 years. The lesions in two cases were limited in the nasal cavity at the first time and on the following examination, one showed epidural mass in the superior orbit（totally resected） and left nasal cavity（ showing obvious enlargement one month later）, another showed wide destruction along the basal cranial bone and intracranial invasion. The third cases appeared as soft tissue mass in the nasal cavity and invading the cavernous sinus and sellar structures combined with destruction of basal cranial bone. Conclusion CT and MRI can provide informations about the position, range and the changes during the following-up of olfactory neuroblastoma,and can accurately evaluate the biological growth behavior of the lesions.
