ABSTRACT: Cerebral abscess is an affection of the nervous system with rare manifestation
in dogs, caused by proliferation of pyogenic bacteria. The aim of this work
was to describe the clinical and pathological findings in a case of cerebral abscess
in dog, as well as to discuss the adopted treatment procedures. A 48-day
old, male labrador dog was examined at the veterinary hospital of the Federal
University of Espírito Santo (UFES), exhibiting a lesion caused by trauma on
the frontal left region of the skull. The animal presented signs of ataxia and
apathy, and received antibiotic and anti-inflammatory treatment. The animal
died 30 days after consultation. Among other macroscopic findings, necroscopic
examination revealed cutaneous scabby lesion on the frontal left region of
the skull, cerebellar herniation, and increase of the left hemiencephalon. Microscopical
analyses showed neutrophilic leptomeningitis of brain, cerebellum
and cord, neuropil vacuolation, and neutrophilic infiltrate in the perivascular
Virchow-Robin spaces of the brain. Staphylococcus sp. was evidenced by microbiological
isolation. The non-specificity of the clinical signs in cases of cerebral
abscess may hinder the establishment of an early diagnosis, thus reducing the
treatment and survival chances of the animal
