“…A high number of congenital pathologies, in the form of multiple hemivertebra and block vertebra, have been documented (Done et al, 1975;Gutierrez-Quintana et al, 2014). The aim of the present study was to determine the prevalence of anomalies in breeds for which the presence of congenital anomalies in the caudal vertebrae is not typical.…”

A prospective study to create radiographic classification of caudal vertebral anomalies in dogs was performed and the prevalence of the disorders estimated. Radiographic examination of the caudal vertebrae was performed in 595 client-owned dogs undergoing routine radiological examination of the hip joints. Anomalies of the caudal vertebrae were divided into four groups: (1) congenital anomalies with aberrant fusion of the vertebral epiphysis, like hemivertebra, block or transitional vertebra; (2) morphological anomalies like vertebra curva and dysplastic vertebral epiphysis; (3) post-traumatic changes, represented by fracture or luxation; and (4) degenerative changes, represented by spondylosis, osteophyte formation and mineralisation of intervertebral spaces. A total of 303 caudal vertebral anomalies were detected in 259 dogs (43.53% of all dogs examined). A single type of vertebral anomaly was present in 215 dogs and a combination of two pathologies was recorded in 44 dogs, which represents 83.01% and 16.99%, respectively, of the affected dogs. Congenital anomaly was present in 11.09% of the dogs examined. Sacrocaudal transitional vertebra was the most common congenital anomaly, present in 12.74% of the affected dogs. Radiographic examination of the caudal vertebrae is recommended as an essential part of any screening process to confirm the presence of congenital anomaly as a cause of kinked tail.

“…A coluna vertebral tem íntima relação com a medula espinhal, artéria vertebral e nervos espinhais, por esse motivo, a alteração anatômica oriunda de hemivértebra pode causar deformidade no canal vertebral, compressão medular ou de raiz nervosa, anormalidad fragilidade dos discos intervertebrais próximos a vértebra defeituosa (DONE et al, 1975;BAILEY & MORGAN, 1992 ), escoliose e cifoescoliose em graus variados, são as angulações da coluna mais frequentemente observadas em porta , raramente se observa lordose (FARROW, 2003 (Fonte: www.vettherapy.com.br).…”

“…Devido à medula ter funções muito localizadas, um mesmo processo patológico pode resultar em apresentações clínicas bem diferentes, dependendo apenas de sua localização (DONE et al, 1975;LeCOUTEUR & GRANDY, 2004). LEAL, D.S.L.…”

“…Esta anomalia surge em decorrência do desenvolvimento assimétrico ou falha nos centros de ossificação de uma ou mais vértebras, originando vértebras de comprimento mais curto ou outras deformidades (DONE et al, 1975).…”

ResumoA hemivértebra é uma anomalia que na maioria das vezes é assintomática, entretanto, é a alteração vertebral congênita que mais frequentemente resulta em sinais neurológicos da medula espinhal. O fato de ser na maioria dos casos um achado radiológico acidental faz com que esta enfermidade seja discutida de forma superficial, a despeito do quadro clínico neurológico grave com a progressão da doença. O objetivo deste trabalho é descrever as causas desta anomalia em cães e gatos, bem como ressaltar a patogenia, os sinais clínicos, os meios de diagnóstico e modalidades de tratamento.Palavras-chave: cães; gatos; neurologia veterinária; hemivértebra. Hemivertebrae in dogs and cats AbstractHemivertebrae is an anomaly that most often is asymptomatic. However, it is the vertebral congenital disease that frequently most results in spinal cord

Mirror writing and reading are rare conditions without definitive mechanisms. 1 A 19-year-old left-handed man had a lifetime history of reading disabilities and mirror writing (figure A). The examination results were unremarkable, with fluent, nonstuttering speech. Brain imaging revealed partial agenesis of the corpus callosum (CC) with a lipoma (figures B and C). Many conditions may present with mirror writing or reading 1,2 ; association with a lipoma and CC agenesis supports the concept that CC abnormalities may be causative. 2 We cannot, however, eliminate causal involvement of the supplementary motor area.
