    Objective:To analyse CT and MRI appearances of lateral ventricular tumors and to explore its differential diagnosis.Methods:49 cases of lateral ventricular tumors were presented in this paper,of them,42 cases proved by pathology,and 7 cases were metastaes known to have primary tumors.The patients were divided into 4 gorups according to tumor′s locations:ventricular trigone,atrium,body and the foramen of Monro,while according to patient′s age:they were divided in 3 groups:<10y,10~30y.>30.Results:(1)The location of tumor was helpful in diferential diagnosis.The most common tumors occurring in ventricular trigone were meningioma,choroid plexus papilloma(CPP),cavernous hemangioma and metastasis.Subependymal giant cell astrocytoma(SGCA) and central neurocytoma frequently occurred in the foramen of Monro.(2)In differentiating the tumors of the trigone and the foramen of Monro,the patient's age was available.CPP was often occurred in children,meningioma in adults and metastasis in old patients.SGCA was commonly seen in children while central neurocytoma was mainly seen in adults.(3)The contrast-enhenced degree of tumors was important in identifying the type of tumors.Both ependymoma and CPP showed obvious contrast enhancement,and giloma and oligodendroglioma tended to enhance in a moderate pattern,while terotoma showed mild or nonenhancement.(4)Part of the tumors had characteristic CT and MRI apperances.Conclusion:The differential diagnosis of lateral ventricular tumors is best determined by consideration of the patient's age,exact intraventricular location of the tumors,the coutrast enhancement degree of tumors,abd tge cgaracterustuc CT and MRI findings of part of the tumors.

    目的:分析侧脑室肿瘤CT和MR表现,探讨其鉴别诊断。方法:49例侧脑室肿瘤,42例经手术病理证实,另7例转移瘤原发灶明确。按部位分为侧脑室三角区、前角、体部和室间孔区,按年龄分为<10岁、11~29岁、>30岁3个年龄组。结果:(1)部位对侧脑室肿瘤的鉴别很有帮助。三角区最常见的肿瘤有脑膜瘤、脉络丛乳头状瘤、海绵状血管瘤和转移瘤。室间孔区最常见的肿瘤有室管膜下巨细胞星形细胞瘤和中枢神经细胞瘤。(2)发病年龄在三角区和室间孔区肿瘤鉴别时很有价值:三角区脉络丛乳头状瘤好发于儿童,脑膜瘤好发于中年人,转移瘤常见于老年人。室间孔区室管膜下巨细胞星形细胞瘤主要见于儿童,而中枢神经细胞瘤主要见于中年人。(3)强化程度对侧脑室体部肿瘤鉴别有重要参考价值:室管膜瘤和脉络丛乳头状瘤强化最显著,星形细胞瘤和少枝胶质瘤呈中度强化,畸胎瘤强化轻或不强化。(4)部分侧脑室肿瘤有较特征性CT和MR表现。结论:肿瘤部位、发病年龄、强化程度和部分肿瘤特征性CT和MR表现是侧脑室肿瘤鉴别诊断的重要方面。
