摘要
目的 对儿童后颅窝肿瘤的临床特征、病理类型、手术切除及术后开发症进行分析。万法回顾分析我院儿童(15岁以下)后颅窝肿瘤30例,术前头颅CT及MRI确定肿瘤位置分别采用咬骨窗开颅(21例)和骨瓣开颅(9例)显微镜下切除肿瘤。结果 全切除肿瘤20例,近全切除肿瘤10例。无手术死亡。术后病理证实:星形细胞瘤9例,髓母细胞瘤14例,室管膜瘤4例,恶性空管膜瘤3例。结论MRI能清楚地显示肿瘤的大小、部位、范围和界限,根据肿瘤不同部位选择最佳的手术入路,显微镜下暴露肿瘤最直视的部位分离肿瘤,可安全地全切除或近全切除肿瘤。
Objective To analyze the clinical manifestation, pathological classification, surgical treament and postoperative complication of the posterior fossa tumors. Methods 30 children (age below 15 years) with the posterior fossa tumor were analyzed retrospectively. Preoperative CT and MRI examination confirmed position of the tumors,the cranieetomy of posterior fossa in 21 cases, the craniotomy in 9 cases were carried out,respectively. All tumors were resected under operating microscope. Results 20 cases got the tumors removed totally, 10 cases removed subtotally. The histological diagnosis was astrocytoma in 9 cases, medulloblastoma in 14 cases, ependymoma in 4 cases, malignant ependymoma in 3 cases. There was no operative mortality. Conclusions MRI may clearly reveal the size, location, range and boundary line of the posterior fossa tumors. The best operative approach was chosen according to the locations of the tumors, and can remove this kind of tumor totally or subtotally under the microscope guidance.
