儿童小脑星形细胞瘤113例分析

Cerebellar Astrocytoma in Children . An Analysis of 113 Cases

1977年2月至1990年2月，术后放疗儿童小脑星形细胞瘤31例。3、5及10年生存率分别为80.6%、71.4及63.6%。

Thirty-one children suffering from cerebellar astrocytomas were irradiated postoperatively from February 1977 to February 1990 . The 3 - , 5 - and 10 - year survival rates were 80 6 % , 71 4 % and 63 3 % .

目的探讨小脑星形细胞瘤的MRI表现，提高对本病的诊断水平。

Objective To investigate the MRI finding of cerebella astrocytoma and to improve the diagnosis ability for this disease .

方法用PCR-DNA单链构型多态性分析（PCR-SSCP）方法，对34例髓母细胞瘤、10例小脑星形细胞瘤和5例正常脑组织进行PTEN基因第5、8重要功能外显子突变检测。

Methods We use polymerase chain reaction-Single strand conformation polymorphism analysis ( PCR-SSCP ) methods to determine the mutations of exon 5 and exon 8 of the PTEN gene in 34 cases of medulloblastoma , 10 cases of cerebellum astrocytoma and 5 cases of normal brain tissue .

目的探讨小儿小脑星形细胞瘤的临床特征、治疗策略和预后。

Objective To investigate the clinical features , therapeutic strategy and prognosis of pediatric benign cerebellar astrocytomas ( BCAs ) .

根据影像学表现将小脑星形细胞瘤分成实体性肿瘤、囊在瘤内型和瘤在囊内型。

We classified the tumour into groups of solid tumor , tumor within a cyst , and cystic tumor according to radiographic results .

结论小脑星形细胞瘤具有特征性，增强扫描有助于病灶检出和定性诊断。

Conclusion MRI findings of cerebella astrocytoma are characteristic and contrast-enhanced scan was helpful in detection of the lesion and characterization of the disease .

目的：了解小脑星形胶质细胞瘤的CT表现。

Objective : To study the CT features of cerebellar astrocytoma .

结论：根据小脑星形胶质细胞瘤特殊表现，结合临床可作出正确诊断。

Conclusion : Bassed on the combination of CT features and clinical manifestations , the accurate diagnosis of cerebellar astrocytoma can be made .

本文报告了儿童小脑星形细胞胞瘤113例，占同期儿童颅内肿瘤的9.4%。肿瘤有囊性变占65.6%。

One hundred and thirteen cases of cerebellar astrocytoma in children account for 9.4 % of all intracranial tumors seen during 1958-1978 . The duration of symptoms usually is long .

目的探讨小脑囊性星形细胞瘤的MRI特征，分析它和病理类型的关系及其外科意义。

Objective To discuss the imaging features of cerebellar cystic astrocytoma , to correlate it with the histopathological findings and to analyze the surgical implications .

目的总结儿童小脑毛细胞型星形细胞瘤的临床资料，探讨其诊治特点。

Objective To summarize the features of cerebellar pilocytic astrocytoma in children .

结论儿童小脑毛细胞型星形细胞瘤有其独特的临床特点，在条件允许的情况下应尽可能切除肿瘤。

Conclusion Cerebellar pilocytic astrocytoma of child has it 's clinical characteristics , and should be totally removed .

方法分析儿童小脑毛细胞型星形细胞瘤15例的影像学、病理学特点及术中所见和预后情况。

Methods The features of images , pathology , surgery and prognosis were analyzed in 15 children cases of cerebellar pilocytic astrocytoma .

结论囊性小脑血管网织细胞瘤MRI表现颇具诊断特征性，但有时需与小脑星形细胞瘤鉴别，实质性肿瘤需注意与转移瘤、髓母细胞瘤及脑膜瘤鉴别。

Conclusion The MRI findings of cyst cerebella hemangioblastoma have diagnostic features . But it should be differentiated from cerebella astrocytoma sometimes . The solid tumor should be differentiated from cerebella metastasis tumor , medulloblastoma and meningioma .
