OBJECTIVES
To evaluate the imaging characteristics of the tumor, emphasizing its location, and to determine the frequency of typical and atypical locations of olfactory neuroblastoma (ONB).
MATERIALS AND METHODS
We retrospectively reviewed the computed tomography and magnetic resonance imaging findings of patients with pathologically proven ONB between April 2000 and April 2023. Demographic information, chief complaints, tumor location, and tumor extension were extracted.
RESULTS
Of the 58 patients, 50 (86.2%) had the epicenter of the mass at the superior part of the nasal cavity, while eight patients (13.8%) had the epicenter at other atypical locations: seven patients (12.1%) at the middle part of the nasal cavity and one patient (1.7%) within both sphenoid sinuses.
CONCLUSION
ONB is not always present in the upper part or the roof of the nasal cavity, and a significant number of ONBs are occasionally found in the rest of the nasal cavity and other atypical locations.
目的
评估肿瘤的影像学特征，重点关注其位置，并确定嗅神经母细胞瘤（ONB）典型和非典型位置的出现频率。
材料与方法
我们回顾性分析了2000年4月至2023年4月间经病理证实为ONB患者的计算机断层扫描和磁共振成像结果。提取了人口统计学信息、主要症状、肿瘤位置和肿瘤范围。
结果
58例患者中，50例（86.2%）肿块中心位于鼻腔上部，8例（13.8%）肿块中心位于其他非典型位置：7例（12.1%）位于鼻腔中部，1例（1.7%）位于双侧蝶窦内。
结论
ONB并不总是出现在鼻腔上部或顶部，相当数量的ONB偶尔会在鼻腔其他部位和其他非典型位置被发现。
