Patologias do cerebelo e plexo coroide: revisão de literatura e relato de caso em um potro

Abstract

The anatomy, histology, physiology and main pathologies of choroid plexus and cerebellum in animals were reviewed. The literature review aims to relate and understand the cerebellum and choroid plexus pathologies, to establish the differential diagnosis among these pathologies in a Mangalarga Marchador foal with changes in the central nervous system. The cerebellar changes described include hypoplasia, abiotrophy and dysplasia; the choroid plexus include the hyperplasia, cholesterol granuloma and neoplasms. The clinico-pathological findings in a foal were comparable to Dandy-Walker syndrome and diffuse villous hyperplasia of the choroid plexus, both described in humans, accompanied by hydrocephalus. The Dandy-Walker syndrome has been described in animals, however, the occurrence of hyperplasia of the choroid plexus of the fourth ventricle was not found in animals.
