The choroid plexus of the fourth ventricle and its arteries
open access
Abstract
The arteries of 15 human brain-stems with cerebelli were injected with coloured gelatine and fixed in 10% formaldehyde solution. The specimens were studied under an operating microscope.
The choroids plexus on each side of the midline was divided into four segments, the medial and lateral horizontal segments and the rostral and caudal sagittal segments, in order to facilitate the description of their blood supply. The anterior inferior cerebellar artery (AICA), the posterior inferior cerebellar artery (PICA) and the superior cerebellar artery (SCA) were the main supplying vessels. AICA supplied the portion of the plexus in the cerebellopontine angles and the adjacent part of the lateral recess of the fourth ventricle through the foramina of Luschka. PICA supplied most of the choroid plexus in the roof and the median opening of the fourth ventricle.
