| Abstract: | Due to the great variations among the shape of the skull in different breeds, the routine use of computed tomography in the diagnosis of central nervous diseases in the dog requires basic knowledge of the structure of the inner subarachnoidal spaces. In neoplastic as well as in inflammatory brain disease, changes of the size and shape of liquor filled spaces can be found. In the present study, the easily demonstrable lateral ventricles of the brain of ten dogs of each breed, respectively, without cerebral disease belonging to the breeds German Shepherd (DSH), Dachshund, Boxer, Labrador Retriever and Toy poodle were characterized with regard to their two-dimensional expansion. The average width and height of the lateral ventricles were ascertained for each breed.The Boxer had the relatively largest lateral ventricles, whereas in the other breeds,their sizes were very similar. 32 of the dogs investigated (64%) had symmetric lateral ventricles, and in 18 dogs (36%) they were asymmetric. Of these 18 cases, the left lateral ventricle was larger in 12 dogs (67%). |
