Hydrochoerus hydrochaeris is the largest rodent with wide distribution in South America. They are often hunted for food purposes and mainly they are victims of road roadkill. There are many descriptive studies of gastrointestinal physiology, parasitism, both ecto- as endoparasites and behavior, but the brain anatomy is poor discussed, with no encephalic studies using imaging methods. Advances in diagnostic imaging modalities had been increasingly progressive in veterinary medicine as well as in wild animals, with the use of computed tomography and magnetic resonance imaging that can provide data and pathological descriptions of intracranial structures in patients in vivo. The aim of this study is to describe the anatomy of intracranial structures in living capybara by means of magnetic resonance imaging providing more detailed information of brain anatomy of this species, for research centers and clinics of wild animals veterinary medicine.
