目的探讨桥小脑角区肿瘤的CT表现及特征,提高对桥小脑角区肿瘤的定性诊断水平。方法回顾性分析47例我院经手术及病理证实的桥小脑角区肿瘤患者的临床资料及CT表现。结果47例中其中听神经瘤26例,脑膜瘤7例,三叉神经瘤6例,胆脂瘤2例,蛛网膜囊肿2例,血管母细胞脑瘤2例,动脉瘤、胶质瘤及转移瘤各1例。桥小脑角区肿瘤中95.7%为脑外病变,4.3%为脑内病变。听神经瘤,脑膜瘤,三叉神经瘤为桥小脑角区常见的肿瘤,该区肿瘤大部分有特征性CT表现,术前定位、定性准确率为89.4%和72.3%。结论桥小脑角区肿瘤有特定的好发部位,CT对该区肿瘤的诊断和鉴别诊断有重要价值。
Objective To investigate the CT manifestations and characteristics of the cerebellopontine angle region tumors and to improve the qualitative diagnosis of the cerebellopontine angle region tumors. Methods The clinical data and CT findings of 47 patients with cerebellopontine angle tumor confirmed by operation and pathology in our hospital were retrospectively analyzed. Results Among the 47 cases, 26 cases were acoustic neuroma, 7 cases were meningioma, 6 cases were trigeminal neuroma, 2 cases were cholesteatoma, 2 cases were arachnoid cyst, 2 cases were hemangiomas, 2 cases were aneurysms, gliomas and metastases One case each. 95.7% of cerebellopontine angle tumors were extracerebral lesions and 4.3% were intracerebral lesions. Acoustic neuroma, meningioma, trigeminal neurinoma is a common tumor in the transverse region of the cerebellopontine angle. Most of the tumors in this region have characteristic CT manifestations. The preoperative localization and the accuracy rate were 89.4% and 72.3% respectively. Conclusions The cerebellopontine angle area tumor has a specific predilection site. CT is of great value in the diagnosis and differential diagnosis of the tumor in this area.
