CT平扫结合MRI扫描在左侧蝶骨嵴脑膜瘤的诊断价值研究

目的探讨CT平扫结合MRI扫描在诊断左侧蝶骨嵴脑膜瘤的临床价值。方法回顾性分析2014年3月-2016年3月经我治疗的36例左侧蝶骨嵴脑膜瘤患者的CT平扫+MRI影像学资料及临床资料病例。结果通过CT平扫+MRI检查显示,36例患者中共检查出37个肿瘤,35例患者为单发。37个肿瘤最大径为1.4cm-6.7cm,平均(4.12±0.3)cm,肿瘤以类圆形或者圆形为主有16个。36例患者中累及前颅窝4例,累及中颅窝7例,累及后颅窝1例。此外有出血状况者2例,17例患者出现坏死、钙化特征。结论 CT平扫结合MRI扫描能够清楚显示蝶骨嵴脑膜瘤的肿瘤的形态学特点及周围重要结构受累情况,术前全面细致地评估肿瘤的各种影像学特征且定性诊断准确率高,对于后期手术方案的制定及术中相关问题的处理及初步判断预后情况具有重要意义。

The Clinical Value of CT+MRI in the Diagnosis of Left Sphenoid Ridge Meningioma

Objective To investigate the clinical value of CT + MRI in the diagnosis of arterio venous alformation.Methods Retrospectively analyze clinical and CT + MRI data of 32 patients with arterio venous malformation in our hospital from March 2014 to March 2016.Results Through the diagnose of CT and MRI, among 36 patients, there are 37 cases of tumors, 35 cases are single. The maximum diameter of tumor ranges 1.4 -6.7cm, the average is (4.12±0.3)cm. There are 16 round tumors. Among 36 patients, there are 4 cases involved in before cranial fossas, 7 cases involved in the middle cranial fossa, 1 case involved in posterior cranial fossa. In addition, there are 2 cases of bleeding condition, 17 cases of necrosis and calcification characteristics.Conclusion CT+MRI can effectively diagnose the Morphological characteristics of sphenoid ridge meningioma tumor and involvement of surrounding vital structures. There is high diagnosis accuracy of comprehensive and detailed preoperative assessment of the various imaging features, and it is of great importance in handling issues related to the case in the development of operation, post-surgery program and preliminary prognosis.
