摘要
目的探讨磁共振成像(MRI)和计算机断层扫描(CT)技术诊断鼻腔鼻窦横纹肌肉瘤的应用效果。方法对经过组织学诊断的50例鼻腔鼻窦横纹肌肉瘤的患者的影像学资料进行回顾性分析,从而制订相应的治疗方法。结果 35例病变中心在蝶筛区,15例病变中心在上颌窦。CT检查结果显示,病变的形态呈现出不规则的状态,边界不清楚,其病变区的密度与周边肌肉区非常相近,且周边的骨质溶骨性骨质破坏,增强后病变区出现不均匀变化;MRI检查结果显示,病变部位T1W1信号略低17例,等比信号3例;病变部位T2W2信号高15例,等比信号5例。增强扫描后,病变的部位呈中度不均匀强化。其中有23例患者的病变部位严重侵犯周围的结构,采用MRI进行诊断,可以清楚看到病变部位所侵犯的领域范围。侵犯眼眶23例,侵犯颅内20例,侵犯海绵窦11例,侵犯鼻咽部10例。手术治疗42例,其中在手术后接受放化疗联合治疗的患者35例,单纯放疗治疗的患者7例。随访6年,死亡5例,37例存活患者的生存时间≥3年。结论 MRI和CT检查各有优势,联合诊断能够提高诊断率。
Objective To explore the application of scanning technology of magnetic resonance imaging and computed tomography of rhabdomyosarcoma in sinonasal cavity. Methods The imaging data 50 cases with rhabdomyosarcoma in sinonasal cavity were retrospective analysised,in order to develop appropriate treatment modalities. Results Lesions of 35 cases were in the center of sphenoid region,15 cases in the maxillary sinus center. Computed tomography（ CT） showed： the morphology of the lesions showed irregular boundary condition,showing the unclear circumstances,the density of the lesions and the surrounding muscle areas were very similar,and the surrounding bone had appeared osteolytic bone destruction situation,uneven changes of lesion after enhancement; magnetic resonance imaging（ MRI） showed： the lesion of T1W1 signal was slightly lower in the case of 17 cases,the emergence of geometric signal in 3 cases; the lesion of T2W2 appeared the high signal in 15 cases,the emergence of geometric signal in 5 cases. After enhanced scan,the lesion showed a moderate inhomogeneous enhancement. The lesion of 23 patients had serious violations of the surrounding structure. Diagnosis by using MRI,we could clearly see the lesion and violations of the field. 23 cases with orbital invasion,20 cases with intracranial invasion,11 cases with invasion of the cavernous sinus,10 cases with nasopharyngeal invasion. The surgical treatment of patients with42 cases,in which post-operative chemotherapy combined with radiotherapy in treatment of patients with 35 cases,radiotherapy alone in the treatment of patients with 7 cases. During the follow-up of 6 years,5 cases died,survival time of 37 cases was more than 3 years. Conclusion Two methods have their advantages,combined diagnosis can improve the diagnosis rate.
