Ataxia is a disorder of coordination, are neurodegenerative diseases affect various neural systems, preferably the cerebellum and its tracks. It is due to dysfunction of the cerebellum or different routes, (cerebellar brain, cerebellum and cerebellar lobby hawthorn) .It ranks with clinical and genetic criteria, with the support but with scarcity neuroimaging studies with quantified methodology. Classify in acquired or hereditary ataxias, can be divided into dominant and recessive. The transmitted by dominant inheritance include spinocerebellar ataxia (SCA.SPINO CEREBELLAR ataxia), which cerebellar degeneration is caused by a genetic disorder mainly by expansion of trinucleotide repeat CAG. This condition is degenerative and is mainly characterized by cerebellar ataxia, incoordination of movements and changes in senior activities such as learning and memory. We describe a SCA type 2 diagnosed adult woman, offering detailed description of the main epidemiological, clinical, genetic and neuroradiological findings.
