5% of malignant extracranial tumours metastasize into the choroid plexus, especially tumours with a higher grade of malignancy. Metastases in the choroid plexus are more frequent than mestastases in the brain corresponding to the relation of weight of choroid plexus and brain. This fact can be explained with the vascularisation by capillaries containing endothelial pores. It remains obscure whether there are other special biochemical or immunological mechanisms too, causing the frequency of metastases in the choroid plexus.
5%的颅外恶性肿瘤会转移至脉络丛，尤其是恶性程度较高的肿瘤。脉络丛中的转移瘤比脑内转移瘤更常见，这与脉络丛和脑的重量关系相对应。这一事实可以用含有内皮小孔的毛细血管的血管化来解释。脉络丛转移瘤频发是否还存在其他特殊的生化或免疫机制仍不清楚。
