Astrocytomas are the most common intracranial neoplasm in children. It is necessary to demonstrate preoperatively the location and extent of a possible neoplastic cyst and to differentiate it from the part that is solid. This is achieved through brain scans, computer axial tomography and angiography. Though of considerable help, brain scan and computer axial tomography are insufficient in providing the neurosurgeon with the complete character and geography of the neoplasm necessary for successful surgical treatment. Demonstration of these features can only be elucidated by contrast angiography. Consequently, the coordination of these three techniques permits the precise evaluation of the presence, nature, and operative and postoperative course of cystic astrocytomas.
星形细胞瘤是儿童最常见的颅内肿瘤。术前必须明确可能存在的肿瘤性囊肿的位置和范围，并将其与实性部分区分开来。这可通过脑部扫描、计算机轴向断层扫描和血管造影来实现。尽管脑部扫描和计算机轴向断层扫描有很大帮助，但它们不足以向神经外科医生提供成功进行手术治疗所需的肿瘤的完整特征和位置信息。这些特征只能通过对比血管造影来阐明。因此，这三种技术的协同使用能够精确评估囊性星形细胞瘤的存在、性质以及手术和术后病程。
