摘要
目的探讨毛细胞型星形细胞瘤的临床诊断和最佳治疗方案及预后。方法通过8病例分析,利用头颅CT、MRI和手术,探讨此类肿瘤的常见部位、临床特点、影像学分型与治疗方案、疗效、预后的关系。结果毛细胞型星形细胞瘤以青少年发病率最高,小脑多见。临床表现主要为颅内压增高、其次小脑症状如共济失调。影像学对分型和手术治疗有指导意义,最后确诊主要依靠病理学。预后与手术切除程度有关。结论毛细胞型星形细胞瘤多发病于青少年,以小脑居首;尽可能全切除肿瘤,其预后良好,可视为"良性肿瘤";若不能全切除的病例,术后可给予放疗亦能达到理想的预后。
Objective To discus the diagnosis ,favorabl management and diagnosis of pilocytastrocytoma. Methods Provided by the information from CT,MRI and operation, we try to discus and confirm the characteristics of this tumor. Results Pilocytastrocytoma commonly occurs in 20 years old or younger. The most frequent location involve by tumor were cerebellum. The most common presenting sympton was increased intracranial pressure ,and then cerebellum symptoms such as incoordination. Final diagnosis made depending on mainly pathology. We found the relationship between prognosis and the extent of surgical removal. Conclusions Pilocytastrocytoma usually occur in children and adolescent. The most common site of these tumors are the cerebellum. And the more complete extent of surgical removal,the better prognosis. So it was called as ＂benign＂ tumors. If pilocyticastrocytoma were subtotally excised, the addition of postoperative irradiati could significantly prolong survival.
