摘要
目的探讨儿童四脑室区肿瘤的MRI诊断价值。方法回顾性分析经手术病理证实的22例四脑室区肿瘤的MRI表现。结果儿童四脑室区肿瘤以髓母细胞瘤、星形细胞瘤和室管膜瘤多见，髓母细胞瘤9例（40．9％），主要呈长T1长T2信号，肿瘤界限模糊不清，强化明显；星形细胞瘤7例（31．8％），多有囊变；室管膜瘤4例（18．2％），呈长T1长T2信号，常有钙化；脉络丛乳头状瘤2例（9．1％），边缘不规则，增强扫描后显示为显著强化。结论MRI对儿童四脑室区肿瘤的诊断和鉴别诊断有重要价值。
Objective To explore MRI diagnostic value oi children tourtn ventricular tumors. Methods MRI features of 22 cases with fourth ventricular tumors confirmed by surgical pathology were retrospectively studied. Results The most common children fourth ventricular neoplasms were medulloblastoma, astrocytoma and ependymoma. Of 22 cases, 9（40.9%） were medulloblastomas exhibited long T1 and T2 signal, ill-defined tumor and marked enhancement; 7（31.8%） astrocytoma, the most had cystic degeneration; 4（18.2 %） ependymoma exhibited long T1 and T2 signal and calcification frequently; 2（9.1%） choroid plexus papilloma exhibited irregular margin and notable enhancement after contrast enhancement. Conclusion MRI have important value for diagnosis and differential diagnosis of children fourth ventricular tumors.
