对第四脑室和桥小脑角的脉络膜丛供血动脉进行了显微解剖。3到2倍。对25具成人尸体的大脑进行了20倍放大。在最常见的模式中，小脑前下动脉（AICA）分支供应脑桥小脑角的脉络膜丛部分和第四脑室外侧隐窝的邻近部分，小脑后下动脉（PICA）分支供应第四脑室外侧隐窝顶部和内侧的脉络膜丛。小脑上动脉（SCA）仅在1个脑内产生脉络膜分支。中线两侧的脉络膜丛分为内侧段和外侧段。每节被认为是2部分，以方便描述其血液供应。内侧段位于第四脑室顶部，分为吻侧或结节部分和尾侧或扁桃体部分。外侧段位于第4脑室外侧隐窝和桥小脑角，分为内侧或脑梗部分和外侧或脑絮体部分。AICA最常供应所有絮状部分和足部外侧部分，PICA最常供应所有扁桃体和结节部分以及足部内侧部分。
The microsurgical anatomy of the arteries supplying the choroid plexus in the 4th ventricle and cerebellopontine angles was examined under .times. 3 to .times. 20 magnification in brains from 25 [human] adult cadavers. In the most common pattern, the branches of the anterior inferior cerebellar artery (AICA) supplied the portion of the choroid plexus in the cerebellopontine angle and adjacent part of the lateral recess of the 4th ventricle, and the posterior inferior cerebellar artery (PICA) supplied the choroid plexus in the roof and medial part of the lateral recess of the 4th ventricle. The superior cerebellar artery (SCA) gave rise to a choroidal branch in only 1 brain. The choroid plexus on each side of the midline was divided into a medial and a lateral segment. Each segment was considered 2 parts to facilitate the description of its blood supply. The medial segment, located in the roof of the 4th ventricle, was divided into a rostral or nodular part, and a caudal or tonsillar part. The lateral segment, located in the lateral recess of the 4th ventricle and cerebellopontine angle, was separated into a medial or peduncular part, and a lateral or floccular part. The AICA most commonly supplied all the floccular part and the lateral portion of the peduncular part, and the PICA most commonly supplied all of the tonsillar and nodular parts and the medial portion of the peduncular part.
