目的：探讨嗅神经母细胞瘤的ＣＴ诊断及鉴别诊断。方法：对９例病人进行鼻窦与头部ＣＴ横断扫描和（或）冠状扫描。结果：９例全部累及鼻腔，其中８例侵及筛窦，３例侵及上颌窦，４例侵及眼眶和颅内脑组织。其ＣＴ主要表现为鼻腔上部软组织肿块影，易侵及筛窦、上颌窦甚至眼眶和颅内脑组织，同时伴有侵及部位的骨质破坏。结论：ＣＴ对典型的嗅神经母细胞瘤能作出准确的诊断，对肿瘤的分期也有很大的价值；但对表现不典型者需与其它肿瘤鉴别。

Objective: To investigate CT diagnosis and differential diagnosis of olfactory neuroblastoma. Methods: CT scan and / or coronal scan of the sinuses and the head were performed on 9 patients. Results: All of the 9 cases involved the nasal cavity, of which 8 cases invaded the ethmoid sinus, 3 cases invaded the maxillary sinus, 4 cases invaded the orbital and intracranial brain tissues. The CT mainly for the upper nasal soft tissue mass, easy invasion and ethmoid sinus, maxillary sinus orbital and intracranial brain tissue, accompanied by invasion of the site of bone destruction. CONCLUSION: CT can make accurate diagnosis of typical olfactory neuroblastoma and is of great value in the staging of tumors. However, CT should be differentiated from other tumors for atypical cases.
