摘要
目的探讨囊虫病在CT平扫及MRI检查中的影像学表现,对其特点进行分析。方法选取在本院2017年9月至2019年6月收治的56例脑囊虫病患者的临床资料进行回顾性分析。所有患者均进行CT平扫及MRI检查。对患者CT平扫及MRI图像表现,以及对两种方法的诊断正确率进行比较。结果 CT平扫检查确诊为囊虫病患者为45例,诊断率为80.35%,明显低于MRI检查确诊55例,诊断率为98.21%,(P<0.05)。诊断以脑实质型为主。CT平扫可见脑实质内囊状低密度影,可见伴头节,多发钙化,MRI可见囊性病灶,内见偏心性等T1、短T2信号头节;增强后,存活期病灶无强化,周围无水肿,变性死亡期病灶囊壁环状强化者,周围伴水肿。结论囊虫病在活动期CT平扫中表现不如MRI明显,在对脑囊虫病病理分期诊断MRI敏感度优于CT平扫,特别是对于囊虫头节的显示也是优于CT,在怀疑是脑囊虫病不能确诊时,建议使用MRI进行进一步检查。
Objective To investigate the imaging features of cerebral cysticercosis in CT plain scan and MRI,and to analyze its characteristics.Methods The clinical data of 56 patients with cerebral cysticercosis admitted to our hospital from September 2017 to June 2019 were retrospectively analyzed.All patients underwent CT plain scan and MRI.The image characteristics of patients in CT scan and MRI,as well as the diagnostic accuracy of the two methods were compared.Results There were 45 patients diagnosed with cysticercosis by CT scan,the diagnosis rate was 80.35%,which was significantly lower than that of MRI(55 cases were diagnosed,the diagnosis rate was 98.21%)(P<0.05).The diagnosis is based on the brain parenchyma.CT scans the brain parenchyma phase,showing multiple calcifications.MRI showed cystic lesions,eccentric scolex with equal T1 and short T2 signal can be seen inside.After the enhancement,the cyst wall and scolex were strengthened,and there is no edema around it.Conclusion The performance of cysticercosis in the CT scan of the active period is not obvious.For the pathological staging diagnosis of cerebral cysticercosis,the sensitivity of MRI is better than that of CT scan,especially for the display of scolex of cysticercosis.When cerebral cysticercosis is suspected and cannot be diagnosed,MRI is recommended for further examination.
