Five cases of histologically confirmed olfactory neuroblastoma (esthesioneuroblastomas) have been studied by computed tomography (CT). Both the clinical symptoms (in particular, unilateral nasal obstruction and recurring epistaxis) and radiological findings (opacity of the paranasal sinuses) are nonspecific. Computed tomography shows a contrast enhancing mass-lesion and is more useful than conventional tomography in estimating its extension and the associated bone destruction, secondary reaction of sinusitis, and tumoral calcification. In the two cases in which the tumor was associated with exophthalmos, CT demonstrated that the muscular cone acts as a barrier preventing tumoral invasion. In cases wtih intracranial involvement, it appears that the attenuation values can be useful for differentiating between invasion by contiguity (two cases) versus metastasis (one case). Computed tomography is valuable in the follow-up and during and after radiotherapy of the tumor.
对5例经组织学确诊的嗅神经母细胞瘤（感觉神经母细胞瘤）进行了计算机断层扫描（CT）研究。临床症状（特别是单侧鼻塞和反复鼻出血）和放射学表现（鼻窦混浊）均无特异性。计算机断层扫描显示有强化的肿块病变，在评估其范围以及相关的骨质破坏、鼻窦炎的继发反应和肿瘤钙化方面比传统断层扫描更有用。在2例肿瘤伴有眼球突出的病例中，CT显示肌锥起到了阻止肿瘤侵犯的屏障作用。在有颅内受累的病例中，衰减值似乎有助于区分连续性侵犯（2例）和转移（1例）。计算机断层扫描在肿瘤的随访以及放疗期间和放疗后都很有价值。
