Casuística das alterações encefálicas diagnosticadas em serviço de patologia veterinária na região Sul do RS

Abstract

Cerebral diseases constitute a significant cause of death in dogs within the veterinary clinical routine. This dissertation addresses cerebral pathologies. The data obtained regarding these illnesses are related to cases diagnosed in the southern region of Rio Grande do Sul. The current study aimed to present the anatomopathological alterations in the brains of dogs based on samples analyzed at the Veterinary Oncology Service of the Federal University of Pelotas (SOVET-UFPel) between 2021 and 2023. This dissertation comprises two articles; the first one discusses the anatomopathological evaluation of cerebral alterations in dogs, where we conducted a comprehensive review of anatomopathological reports of dogs diagnosed with neurological changes, obtained through necropsies, from August 2021 to April 2023, within the scope of the Veterinary Oncology Service at the Federal University of Pelotas. We collected and thoroughly assessed information related to clinical history, gender, and age. Additionally, the identified histological alterations were carefully categorized according to the anatomical region of the nervous system and in accordance with the DINAMIT-V acronym. Out of a total of 1546 cases diagnosed during this period, 27 presented cerebral alterations. The second article reports a metastatic gemistocytic astrocytoma in a mixed-breed male dog of approximately four years of age, confirmed through necropsy, where it was possible to visualize macroscopic and microscopic lesions consistent with gemistocytic astrocytoma.
