“…4,5 Dogs with presumptive ANNPE typically present with a peracute onset of spinal cord dysfunction that is non-progressive after 24 h. 1,2 Clinical signs are often strongly lateralised, and mild-to-moderate spinal hyperaesthesia may be seen in approximately half of affected cases. 2,6 Definitive diagnosis of ANNPE can only be confirmed by histopathology. 1 However, MRI can be used to make a presumptive diagnosis with specific characteristics identified to reach a presumptive ante-mortem diagnosis of ANNPE.…”

17Objectives: The aim of the study was to describe the clinical features, diagnostic imaging 18 findings, treatment and outcome in cats diagnosed with presumptive acute non-compressive 19 nucleus pulposus extrusion. Results: Eleven cats met the inclusion criteria. All cats had a peracute onset of clinical signs, 25with eight cats experiencing witnessed (n = 6) or suspected (n = 2) external trauma.

“…Pode ocorrer a extrusão (Hansen tipo I) ou protrusão (Hansen tipo II) do disco para o interior do canal vertebral. Tanto na doença de Hansen tipo 1 quanto na de Hansen tipo 2 ocorre compressão da medula espinhal (Risio et al, 2014;. A extrusão do disco intervertebral (EDIV) ou Hansen tipo I geralmente acontece quando o disco intervertebral sofre degeneração condroide e envolve a migração hiperaguda do material do núcleo pulposo através de todas as camadas do anel fibroso rompido para o interior do canal vertebral (Figura 2) (Jeffery, 1995).…”

A neurologia é a especialidade que cresce cada vez mais dentro da medicina veterinária, visto que as afecções neurológicas são comumente encontradas na clínica de pequenos animais. No entanto, muitas doenças neurológicas podem ser tratadas de maneira significativa. Principalmente quando o diagnóstico é realizado precocemente, e o tratamento logo iniciado, podendo ser clínico ou cirúrgico. Uma das afecções mais comum que acometem o sistema nervoso central é a doença do disco intervertebral (Hansen tipo I), caracterizada pela extrusão do disco intervertebral, provocando alterações neurológicas em cães, principalmente nos cães de pequeno porte. Nesse caso, quando o tratamento é cirúrgico, há várias abordagens cirúrgicas relatadas na literatura, sendo a hemilaminectomia a técnica cirúrgica mais comumente utilizada para a descompressão da medula espinhal. Dessa forma, por ser uma doença de alta severidade, este artigo tem como objetivo relatar as principais características desta enfermidade e o uso da técnica de hemilaminectomia para seu tratamento, no qual o prognóstico depende do grau de lesão neurológico, associado ao pós-operatório.

IntroductionPorencephaly is defined as a fluid-filled cavity of variable size in the brain cortex. It is regarded as a congenital condition and is typically considered a developmental or an encephaloclastic defect. Our hypothesis is that postnatal traumatic events in the first few months of life may represent a cause of canine and feline porencephaly that is more common than generally suspected. The aims of this study were to retrospectively investigate porencephaly in a large population of dogs and cats, detect MRI features that might be useful to differentiate postnatal acquired traumatic forms from congenital/perinatal porencephaly, and define the prevalence of seizure activity in porencephalic patients.Materials and methodsThis is a double-center, descriptive, retrospective case series. Databases were searched for cases within a 17-year time span that involve dogs and cats with an MRI-based diagnosis of cerebral cavitary lesions. Animals were included if a complete signalment and an exhaustive MRI of the brain were available. Besides the porencephalic lesions, MRIs of the head were reviewed to detect concomitant musculoskeletal abnormalities.ResultsThirty-two cases involving nine cats and twenty-three dogs were selected. Of all the cases, 21.9% were aged six years or older at the time of diagnosis. All patients in which the neuroanatomical localization was available showed clinical signs of a prosencephalic disorder. Epileptic seizures were observed in 71.8% of cases. A single porencephalic cavity was found in 78.1% of cases. The most affected cerebral lobe was the parietal lobe (n = 20). The defects involved both the grey and white matter in 78.1% of cases. Twenty cases showed concomitant musculoskeletal abnormalities overlying the porencephalic cavities. Fourteen of twenty cases showed evidence of fractures, of which thirteen showed depression of the calvarium and twelve masticatory muscle abnormalities. Of these, seven of fourteen had a history consistent with a head trauma in the first period of life.ConclusionThe recognition of skull fractures and muscular abnormalities closely associated with the porencephalic cavity may support a diagnosis of a postnatal traumatic origin of porencephaly. Therefore, this study highlights the importance of evaluating musculoskeletal structures in the MRIs of the heads of porencephalic cases.
