磁共振成像在眼眶肿瘤及肿瘤样病变中的诊断价值

Diagnostic value of MRI in orbital tumors and tumor-like lesions

目的分析磁共振成像(MRI)检查在眼眶肿瘤及肿瘤样病变中的诊断价值。方法回顾性分析河南省开封市中心医院自2017年8月至2022年8月60例眼眶肿瘤及肿瘤样病变患者的临床病理及影像学资料。观察病变位置、形态、信号及强化方式等特征,以提高MRI诊断眼眶肿瘤及肿瘤样病变的准确率。结果经MRI检查诊断3例混合瘤和5例泪腺癌,9例海绵状血管瘤,5例神经鞘瘤,4例淋巴瘤,3例神经纤维瘤,2例皮样囊肿,11例脑膜瘤,8例炎性假瘤,2例静脉曲张,2例黏液囊肿,3例胶质瘤,误诊3例。MRI诊断60例眼眶肿瘤及瘤样病变的准确率为95%(57/60),与病理诊断结果比较差异无统计学意义(P>0.05)。结论MRI检查能准确显示眼眶肿瘤及瘤样病变的发病部位、形态及周围组织关系,还能提供组织内部信号等影像学特征,有利于眼眶肿瘤及瘤样病变的诊断及鉴别诊断。

Objective To analyze the diagnostic value of MRI in orbital tumors and tumor-like lesions.Methods The clinicopathological and imaging data of 60 patients with orbital tumors and tumor-like lesions in our hospital from August 2017 to August 2022 were retrospectively analyzed.The characteristics like lesion location,morphology,signal,and enhancement pattern were observed to improve the diagnostic accuracy of MRI.Results According to MRI findings,three patients were diagnosed with mixed tumor,five with lacrimal gland adenocarcinoma,nine with cavernous hemangioma,five with schwannoma,four with lymphoma,three with neurofibroma,two with dermoid cyst,eleven with meningioma,eight with inflammatory pseudotumor,two with varicose veins,two with mucous cyst and three with glioma;the remaining three were misdiagnosed.The accuracy of MRI in diagnosing orbital tumours and tumour-like lesions in 60 cases was 95%(57/60),and the difference was not statistically significant when compared with pathological findings(P>0.05).Conclusion MRI can accurately show the location,morphology and relationship of the surrounding tissues of orbital tumours and tumour-like lesions,as well as provide internal signal and other imaging features,which are useful for the diagnosis and differential diagnosis of orbital tumours and tumour-like lesions.
