本文报告作者亲自诊断和处理的脉络丛乳头状瘤22例。描述脉络丛乳头状瘤的血管造影诊断和扩展，以及从侧脑室、第三脑室和第四脑室切除这些肿瘤的外科技术。特别注意使用血管造影术作为外科手术技术选择的研究。侧脑室脉络丛乳头状瘤的诊断是通过观察脉络膜前动脉肥厚的存在，一个肿瘤位于三角区，另一个位于颞角或额角，三角区肿瘤染色，以及不对称性脑积水，通常偏离大脑室一侧。后颅窝乳头状瘤导致对称性脑积水，肿瘤染色通常位于中线，主要供血来自小脑上动脉或小脑后下动脉。手术切除肿瘤需要在闭塞供血和引流血管后进行“整块”切除。肿瘤位于侧脑室时应直接切除，位于后颅窝时应行脑室-脑脊液分流术。
This is a report of 22 cases of papillomas of the choroid plexus diagnosed and managed personally by the author. The angiographic diagnosis and extension of choroid plexus papillomas are described, as is the surgical technique for removing these tumors from the lateral, third, and fourth ventricles. Specific attention is given to using the angiogram as the study of choice upon which surgical technique is planned. The diagnosis of choroid plexus papilloma of the lateral ventricle is made by observing the presence of a hypertrophied anterior choroidal artery, a 'double tumor' sign with one tumor at the trigone and the other within the temporal or frontal horn, tumor stain at the trigone, and asymmetrical hydrocephalus, generally, with a shift away from the side of the larger ventricle. Posterior fossa papillomas cause symmetrical hydrocephalus and generally have tumor stain located within the midline, with the major feeding coming from either the superior cerebellar or the posteroinferior cerebellar arteries. Surgical removal of the tumor should entail an 'en bloc' resection following occlusion of the feeding and draining vessels. The tumor should be removed directly when it is in the lateral ventricle and following ventriculocerebral spinal fluid shunting when it is in the posterior fossa.
