Conselho Nacional de Desenvolvimento Científico e Tecnológico / A retrospective study including the analysis of the cerebrospinal fluid (CSF) of dogs
neurologically affected was conducted by the Neurology Service (NS) of the Veterinary Teaching
Hospital (VTH) at the Federal University of Santa Maria (FUSM), between 2004 and 2015. The aim
of this study was to analyze the results of the CSF of dogs with neurological signs, and compare the
changes found in the CSF in two sampling sites in the same patient and see if this test helped the
clinician to strengthen clinical suspicion of the major diseases of the central nervous system. Of the
507 patients that underwent CSF analysis, only the analysis of 144 (26.5%) dogs were suited to
inclusion criteria. The main diagnosed neurological diseases were distemper (21.6% [n=31]),
intervertebral disc disease (IVDD) (52.7% [n=76]), intracranial (IC) tumors (13.2% [n=19]) and
tumors which affected the spinal cord (SC) (8.3% [n=12]). Lymphocytic pleocytosis was present in
78.3% (29/37) of samples from dogs with canine distemper and in 23.2% (10/43) of samples from
dogs with IVDD. The albuminocytologic dissociation was found in 73% (19/26) of samples from dogs
with IC tumors and in 64.3% (9/14) of the samples from dogs with tumors involving the SC. For dogs
affected by IVDD, there was statistical significance (p <0.05) between the degree of neurological
dysfunction and the total nucleated cells (TNC) and total protein (TP). In 29 dogs, CSF was collected
from both the cistern magna (CM) and the lumbar cistern (CL) and in 12 (41.4%) the results were
different between the samples of the same dog, where two cases (6, 9%) showed alterations in the
sample collected cranial to the injury. It can be concluded that the lymphocytic pleocytosis was the
main alteration found in the CSF of dogs with distemper and IVDD and albuminocytologic
dissociation in tumors, intracranial and affecting the spinal cord. Dogs affected by IVDD had more
severe neurological signs as TNC and TP increased and the CSF was altered even collected cranial to
the lesion site and helped the clinician to strengthen the clinical suspicion., but not confirm, the major
neurological diseases in dogs. / Foi realizado um estudo retrospectivo dos resultados do líquido cerebroespinhal (LCE) de
cães, atendidos pelo Serviço de Neurologia (SN) do Hospital Veterinário Universitário (HVU) da
Universidade Federal de Santa Maria (UFSM), de 2004 a 2015, com o objetivo de analisar os
resultados obtidos do LCE de cães com sinais neurológicos, e comparar as alterações encontradas no
LCE em dois locais de colheita no mesmo paciente e verificar se esse exame auxiliou o clínico em
reforçar a suspeita clínica das principais doenças do sistema nervoso central. Dos 507 pacientes que
foram submetidos à análise do LCE, apenas as análises de 144 (26,5%) cães se adequaram aos
critérios de inclusão. Dentre estes, cães com cinomose representaram 21,6% (n=31), doença do disco
intervertebral (DDIV) 52,7% (n=76), tumores intracranianos (IC) 13,2% (n=19) e tumores envolvendo
a medula espinhal (ME) 8,3% (n=12). A pleocitose linfocítica esteve presente em 78,3% (29/37) das
amostras de cães com cinomose e em 23,2% (10/43) das amostras de cães com DDIV. Já a dissociação
albuminocitológica foi encontrada em 73% (19/26) das amostras de cães com tumores IC e em 64,3%
(9/14) das amostras de cães com tumores envolvendo a ME. Para os cães acometidos pela DDIV,
houve significância estatística (p < 0,05) entre o grau de disfunção neurológica e o total de células
nucleadas e total de proteínas encontrados no LCE destes cães. Em 29 cães, houve a colheita do LCE
tanto na cisterna magna (CM) quanto na cisterna lombar (CL) e em 12 (41,4%) os resultados foram
diferentes entre as duas amostras colhidas do mesmo cão, onde dois (6,9%) apresentaram alteração na
amostra colhida cranial à lesão. Pode-se concluir que a pleocitose linfocítica foi a principal alteração
encontrada no LCE de cães com cinomose e DDIV e dissociação albuminocitológica nas neoplasias,
intracranianas e medulares, cães acometidos pela DDIV apresentaram sinais neurológicos mais
severos conforme o TCN e o TP aumentaram e o LCE sofreu alteração, mesmo colhido cranial ao
local da lesão e auxiliou o clínico em reforçar a suspeita clínica, mas não confirmou, as principais
doenças neurológicas em cães.
