嗅神经母细胞瘤的CT诊断

Diagnosis of esthesioneuroblastoma with CT

目的探讨CT在嗅神经母细胞瘤诊断和分期中的价值。方法回顾性分析7例经病理证实的嗅神经母细胞瘤的CT表现和临床资料。结果按Kadish分期标准,本组7例中2例为B期,5例为C期。病灶侵及鼻腔7例,同侧筛窦6例,对侧筛窦5例,上颌窦4例,眼眶3例,前颅窝2例。CT增强扫描5例,4例为中度均匀强化,1例轻度均匀强化,2例颅内病变不均匀强化。结论横断面及冠状面CT扫描可清晰地显示嗅神经母细胞瘤部位及向周围侵犯的范围,能对肿瘤进行正确的分期,以便于临床制定合理的治疗方案。

Objective To assess role of CT in the diagnosis and staging of esthesioneuroblastoma. Methods The CT findings and the clinical data of 7 cases of esthesinneurnhlastuma confirmed by pathology were analyzed retrospectively. Results According to Kadish staging criteria, 2 cases were at stage B, 5 cases were at stage C, 7 cases were invaded into nasal cavity, 6 into ipsilateral ethmoid sinus, 5 into contralateral ethmoid sinus, 4 into maxilIary sinus, 3 into orbit and 2 into anterior cranial fossa. In the 5 cases of enhanced CT, 4 were moderately and evenly enhanced, 1 was slightly and evenly enhanced, and 2 were unevenly enhaaned intracranially, Conclusion CT scan with transverse and coronal section is able to clearly location and invasion of esthesinneuroblastorna and correctly stage the tumor, helping clinicians to make rational therapy plan.
