摘要
目的分析颅内鞍区肿瘤CT、MRI的影像表现及诊断意义。方法收集本院2017年1月至2019年10月收治的55例经影像学检查发现颅内鞍区肿瘤后经手术病理检查确诊患者的临床资料,收集CT、MRI检查图像,对CT、MRI图像进行分析,总结颅内鞍区肿瘤影像特征,以病理检查结果为基准,计算CT及MRI检查对颅内鞍区肿瘤检出正确率。结果CT对颅内鞍区肿瘤检出正确率为87.27%(48/55),MRI检出正确率为96.36%(53/55),CT稍低于MRI但比较差异无统计学意义(P>0.05);影像学表现:鞍内或鞍上属于鞍区肿瘤多发区域,CT平扫多为边缘清晰类圆形影,MRI脑膜瘤可见脑膜“尾”征,MRI垂体瘤可见“束腰”征。结论颅内鞍区肿瘤影像学多样,CT及MRI在颅内鞍区肿瘤诊断中均有较高使用价值,在临床中两者可结合使用,可有效提高颅内鞍区肿瘤诊断准确性。
Objective To analyze the CT and MRI imaging manifestations and diagnostic significance of tumors in intracranial sellar region.Methods The clinical data of 55 patients with tumors in intracranial sellar region diagnosed by surgical pathological examination were collected from January 2017 to October 2019.The CT and MRI images were collected,the CT and MRI images were analyzed.The characteristics of tumors in intracranial sellar region were summarized.Based on the results of pathological examination,the accuracy of CT and MRI examinations in detecting tumors in the tumors in intracranial sellar region was calculated.Results The accuracy of CT in detecting tumors in intracranial sellar region was 87.27%(48/55),and the accuracy of MRI was 96.36%(53/55).The accuracy of CT was slightly lower than that of MRI,but there was no statistical significance(P>0.05).Imaging findings:Intrasellar and suprasellar part was high-frequency region of tumors in intracranial sellar region.CT plain scans were mostly round-shaped shadows with clear edges.The MRI of meningioma showed"meningeal tail sign",and the MRI of pituitary tumor showed"beam waist sign".Conclusion The imaging of intracranial saddle area tumors is diverse.CT and MRI have high value in the diagnosis of tumors in intracranial sellar region.In clinic,they can be combined to use to effectively improve the diagnostic accuracy of tumors in intracranial sellar region.
