“…The results of this study suggest a correlation between dilation of the lateral ventricles and olfactory bulb cavities, as reported in dogs (Kim et al 2009). However, unlike cats, dogs showed neurological signs (Kim et al 2009), since the expansion of the olfactory bulb cavities in these animals is associated with increased intracranial pressure at later stages (Platt & Garosi 2012, Laubner et al 2015. Intracranial pressure was not measured in this research; however, imaging findings related to increased intracranial pressure, such as periventricular edema and thinning of the grooves and/or subarachnoid space were not observed (Laubner et al 2015).…”

RESUMO.-[Alterações senis dos ventrículos cerebrais de gatos domésticos hígidos.] O estudo objetivou a determinação das alterações senis dos ventrículos cerebrais de gatos domésticos hígidos não braquicefálicos pela aquisição de imagens encefálicas de 12 indivíduos adultos (1 a 6 anos), 11 maduros (7 a 11 anos) e 10 geriátricos (12 anos de idade ou mais) por ressonância magnética. Nossa hipótese é de que o sistema ventricular dos gatos se expande com o avanço da idade. A possibilidade de evidenciação das cavidades do bulbo olfatório e dos cornos temporais dos ventrículos INDEX

“…Na forma congênita, o animal nasce com sinais clínicos evidentes para a doença, tais como: estrabismo ventrolateral bilateral, alterações de comportamento e nível de consciência, andar em círculos, crises convulsivas, cegueira cortical e aumento do tamanho do crânio com fontanelas abertas (Lorenz et al, 2011). Já na forma adquirida, normalmente é secundária a alguma doença que cause obstrução total ou parcial do líquor, como neoplasias, traumatismo, edemas cerebrais ou agentes infecciosos que causem encefalite ou meningite (Oliver et al, 1997).…”

RESUMO O objetivo deste trabalho foi relatar um caso raro de hidrocefalia em um felino doméstico, da raça Persa, de 30 dias de idade. O animal foi atendido com histórico de impossibilidade de manter-se em estação, incoordenação motora, inabilidade para se alimentar sozinho e sustentar o peso da cabeça. No exame clínico, foi observada presença de fontanela aberta, aumento de calota craniana, ataxia, estrabismo unilateral e secreção ocular. A realização de ultrassonografia do crânio levou à confirmação do diagnóstico de hidrocefalia. O paciente permaneceu internado, sendo o protocolo de tratamento empregado constituído de corticosteroide, diurético e protetor gástrico em alta dose, além de alimentação por via oral e fluidoterapia. O animal veio a óbito após 24 horas, sendo encaminhado para realização de necropsia.

“…Each lateral ventricle presents three horns: an anterior or frontal horn extending to the frontal lobe, a posterior or occipital horn extending to the occipital lobe and an inferior or temporal horn extending into the temporal lobe. The floor of the lateral ventricles' central part consists inferiorly of the caudate nucleus and posteriorly of the hippocampus [1,7]. The ventricular system is filled by the CSF, which is easily identified in an ultrasonographic (US) image as hypoecogenic and in computed tomography (CT) as hypodense [6,[8][9][10].…”

Objectives: The brain's inner cavities containing cerebrospinal fluid are referred to as ventricles, which are easily identified in an ultrasonographic (US) image as hypoecogenic and in computed tomography (CT) as hypodense. Imaging has become essential to planning and neuronavigation in brain surgeries, serving to guide the surgeon through the organ. The study aimed to 1) compare ultrasonography (US) and computed tomography (CT) measurements of lateral ventricle volumes (LVV) in dogs to determine their level of agreement and 2) understand their influence on surgical planning and neuronavigation. Materials and methods:Measurements were taken from a sample of 24 LVVs from 12 brachycephalic dog cadavers. First, 2 mm slices of the dogs' brains were scanned with the CT machine. The US brain scan technique was performed using a transducer of 7.5 MHz over the brain after craniotomy placement. This procedure was useful in simulating the brain neuronavigation technique in a two-dimensional scenario. A P value less than 0.05 was defined as statistically significant. Results:A comparison of the US and CT images showing measurements of the right and left LVVs showed no statistically significant differences between the LVVs, allowing us to conclude that US is a reliable technique to planning and neuronavigation in brain surgeries. Conclusion:As a result US is of great value in the everyday practice and areas working with limited resources such as in veterinary medicine, or even in a zooubitquity context, since in some human's hospitals of developing countries or in some rural and remote areas, access to CT, magnetic resonance MR techniques, and neuronavigation systems are limited to point high-technology centers, unlike the sonography (US). Therefore, US it is a reliable technique to planning and neuronavigation in brain surgeries, thus promoting patient safety and surgeon success.
