目的 评价CT诊断嗅神经母细胞瘤的作用。方法 回顾性分析 7例经手术或活检诊断的嗅神经母细胞瘤的CT表现。结果 按Kadish标准分期 ,本组 7例嗅神经母细胞瘤中 6例为C期 ,1例为B期 ,病灶均位于鼻腔顶部 ,均侵犯鼻窦、眼眶和前颅窝或中颅窝。 4例增强扫描中 3例明显不均匀强化 ,1例中度强化。结论 CT扫描可明确嗅神经母细胞瘤的侵犯范围和程度 ,并对肿瘤进行正确的分期 ,对临床决定治疗方案具有重要的参考价值。
Objective To evaluate the role of CT in the diagnosis of olfactory neuroblastoma. Methods The CT findings of 7 cases of olfactory neuroblastoma diagnosed by surgery or biopsy were retrospectively analyzed. Results According to Kadish standard staging, 6 cases of olfactory neuroblastoma in this group were C stage and 1 case was B stage. The lesions were located on the top of the nasal cavity, both of which infiltrated the sinuses, orbit and anterior fossa or middle cranial fossa. In 4 cases, 3 cases were obviously non-uniform enhancement and 1 case moderate enhancement. Conclusion The CT scan can confirm the scope and degree of the invasion of neuroblastoma and correct the staging of the tumor, which has an important reference value for the clinical treatment decision.
