Neoplasias do sistema nervoso central de caninos e felinos

Abstract

Central nervous system (CNS) diseases can be of infectious, degenerative, idiopathic and neoplastic origin. Neoplasms are the third most frequent cause of neurological disorders in the dog and cat clinic. They can be primary from the nervous tissue or secondary to metastases and tumor expansion, with meningioma being the most frequent primary tumor and breast carcinoma metastasis the most frequent secondary one. In small animals there is no predisposition regarding sex, race or age, although the highest occurrence of CNS neoplasms is observed in adult and elderly animals. Although neoplasms are of great importance, there are few studies that specifically cover the epidemiological and pathological parameters of different neurological neoplasms. Thus, the present thesis aimed to carry out an epidemiological and pathological study of neurological neoplasms diagnosed in canines and felines at the Regional Diagnostic Laboratory of the Faculty of Veterinary, Federal University of Pelotas (LRD/FV/UFPel), in the period of 2000. to 2020. Taking into account the objectives, the thesis consists of three articles, two on secondary neoplasms with metastases to the central nervous system and an epidemiological study on CNS neoplasms in dogs and cats diagnosed at LRD/FV/UFPel.
