目的探讨CT在鉴别小脑肿瘤与小脑亚急性出血中的价值。方法回顾性分析2011年10月至2014年10月间收治的23例行手术病理证实的、CT检查与小脑亚急性出血相似的小脑肿瘤临床资料,比较其在CT平扫方面的表现及各自特点。结果 23例患者中,脑转移瘤8例,占34.8%;脑膜瘤5例,占21.7%;髓母细胞瘤3例,占13.0%;室管膜瘤3例,占13.0%;脉络丛乳头状瘤2例,占8.7%;星形细胞瘤2例,占8.7%。CT检查结果均显示高密度或略高密度为主的低密度水肿或囊性病变,此临床征象与小脑亚急性出血的表现基本相似。该组患者术前有9例被误诊为小脑出血,占39.1%;10例考虑为小脑出血,占43.5%;2例考虑为小脑肿瘤合并出血,占8.7%;2例诊断结果为小脑占位,占8.7%。结论小脑肿瘤与小脑亚急性出血在CT平扫方面有不同的CT表现,临床医师对其进行准备分析,有利于对两种疾病的鉴别诊断。
Objective To investigate the value of CT in differentiating cerebellar tumors from cerebellar subacute hemorrhage. Methods The clinical data of 23 patients with cerebellar neoplasms similar to cerebellar subacute hematomas confirmed by surgery and pathology confirmed from October 2011 to October 2014 were retrospectively analyzed. Their CT features and their respective features were compared . Results Among the 23 patients, 8 were brain metastases (34.8%), 5 were meningiomas (21.7%), 3 were medulloblastomas (13.0%), 3 were ependymomas (13.0%), and choroid plexus 2 cases were found as tumor, accounting for 8.7%. 2 cases were astrocytoma, accounting for 8.7%. CT examination showed high density or slightly high density-based low-density edema or cystic lesions, the clinical signs and performance of cerebellar subacute bleeding are basically similar. The group of patients were misdiagnosed as cerebellar hemorrhage in 9 cases before operation, accounting for 39.1%; 10 cases were considered as cerebellar hemorrhage, accounting for 43.5%; 2 cases were considered cerebellar tumors with bleeding, accounting for 8.7%; 2 cases were cerebellar masses , Accounting for 8.7%. Conclusion Cerebellar neoplasms and cerebellar subacute hemorrhage have different CT manifestations in CT scan. Clinicians prepare them for analysis, which is good for the differential diagnosis of the two diseases.
