Abstract

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.

嗅神经母细胞瘤并非总是位于鼻腔顶部

目的：评估肿瘤的成像特征，重点是肿瘤的位置，并确定典型和非典型位置嗅神经母细胞瘤的发生频率：评估肿瘤的影像学特征，强调肿瘤的位置，并确定嗅神经母细胞瘤（ONB）典型位置和非典型位置的频率：我们回顾性研究了 2000 年 4 月至 2023 年 4 月期间经病理证实的嗅母细胞瘤患者的计算机断层扫描和磁共振成像结果。结果：58 名患者中，50 人（86%）的病理证实为 ONB：58例患者中，50例（86.2%）的肿块中心位于鼻腔上部，8例（13.8%）的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鼻腔顶部，偶尔也会在鼻腔其他部位和其他非典型位置发现大量 ONB。
