| Abstract | |
The aim of this study was to describe the anatomy of intracranial structures in living capybara (Hydrochoerus hydrochaeris) by means of magnetic resonance imaging (MRI) providing more detailed information of brain, eye and orbit anatomy of this species. Eight capybaras and two anatomic encephalic specimens were used for the descriptive study comparing them with domestic animals and other rodents, observing reduction of the sulcus and gyrus, prominent olfactory bulb and pituitary, and presence of the olfactory ventricle. In addition, ocular bulb and orbit of these animals were also evaluated, obtaining the (+ SD) of the axial length of the eye bulb of 24.1 + 1.8 mm, anterior chamber depth of 2.8 + 0.6 mm, lens thickness of 8.5 + 0.7 mm, and optic nerve thickness of 2.6 + 0.6 and 2.9 + 0.6 mm from proximal to distal portion, respectively. In conclusion, capybaras had sulcus and gyrus in a greater proportion than other rodents and the hypophysis and olfactory bulb were more extensive when compared to domestic animals. In addition, the orbital structures presented better detail on T1 MR images and that measurements used in the ultrasound routine can be used as a complement for the study of the orbit of capybaras by means of MRI exams.
