-We analyze the results of surgical treatment of 60 patients presenting syringomyelia (SM) associated with Chiari malformation (CM) who were operated in the period 1982-2000. For each case, analysis covered 15 signs and 16 symptoms included in a protocol that separated SM signs and symptoms from those of CM. A score system was established in parallel with the protocol to make the evaluation of treatment results easier. All cases were submitted to craniovertebral decompression by C1 and eventually C2 laminectomy and cerebellar tonsillectomy with duramater graft. To evaluate the results, statistical proportion difference tests and variance analyses were made to a reliability index of 95% (p=0.05). We conclude that the statistical improvement of CM signs and symptoms was very significant (p=0). Syringomyelia signs and symptoms also improved significantly, except for "upper limb hyporeflexia", which did not improve. No statistical difference in the improvement of SM symptoms as compared to CM symptom was found. Syringomyelia signs improved statistically more than CM signs. In half of patients, the percent improvement of signs and symptoms ranged between 40% and 60%.KEY WORDS: syringomyelia, Chiari malformation, surgical treatment.Resultados do tratamento da siringomielia associada com malformação de Chiari: análise de 60 casos RESUMO -Analisamos os resultados do tratamento cirúrgico de 60 pacientes com a associação de siringomielia (SM) e malformação de Chiari (MC) operados no período de 1982 a 2000. Em cada caso foram analisados 15 sinais e 16 sintomas, incluídos em um protocolo que separou os sinais e sintomas decorrentes da SM dos sinais e sintomas decorrentes da MC. Paralelamente ao protocolo, foi elaborado um sistema de pontuação que facilitou a avaliação dos resultados do tratamento. Todos os casos foram submetidos à descompressão crânio vertebral com laminectomia de C1 e eventualmente de C2, e tonsilectomia cerebelar com plásti-ca de dura-máter. Para avaliação dos resultados, foram aplicados testes estatísticos de diferença de proporções e análise de variância com confiabilidade de 95% (p=0,05). Concluímos que os sinais e sintomas da MC apresentaram melhora estatística muito significativa (p=0). Os sinais e sintomas decorrentes da SM também apresentaram melhora significativa, sendo a exceção o sinal "hiporreflexia de membros superiores" que não melhorou. Não encontrada diferença estatística da melhora dos sintomas da SM quando comparados aos da MC. Os sinais na SM melhoraram estatisticamente mais que os sinais da MC. A metade dos pacientes apresentou percentual de melhora de seus sinais e sintomas na faixa entre 40 e 60%. PALAVRAS-CHAVE: siringomielia, malformação de Chiari, tratamento cirúrgico. Syringomyelia (SM) and Chiari malformation (CM) are two clinical syndromes showing a number of characteristics. The study of these two pathologies, when associated with each other, leads the researcher to face a high number of signs and symptoms, thus making the analysis of surgical treatment results of both...

“…Pain is an important clinical sign reported to occur in 80% of humans with syringomyelia and 35% of dogs with syringomyelia [18,19,26]. However, in dogs, pain may be difficult to localize during clinical examination, as it is often intermittent.…”

ABSTRACT. This report describes the use of magnetic resonance imaging (MRI) to diagnose cervical syringomyelia in 4 cats. MRI revealed enlargement of the lateral ventricle in all the cats. Of the 4 cases, MRI revealed herniation of the cerebellum in 3 cats, an isolated fourth ventricle in 1 cat, severe hydrocephalus in 2 cats and brain masses in 1 cat. In this report, the cervical syringomyelia in these cats may have been due to formation of a secondary syrinx (enlargement of the central canal) as a result of blockage of flow in the outlet of the fourth ventricle caused by FIP encephalomyelitis or secondary cerebellar tonsillar herniation caused by increased intracranial pressure due to intracranial masses or may have been due to caudal compression of the cerebellum caused by increased intracranial pressure due to hydrocephalus.KEY WORDS: feline, magnetic resonance imaging (MRI), syringomyelia.
