| Summary: | The author reports the case of a 54-year-old male patient with a pontine hematoma and with the one-and-a-half syndrome, cerebellar ataxia and no signs of pyramidal tract involvement. The absence of involvement of the pyramidal tract in the case reported herein is likely due to variation in the vascular anatomy of the pons. The pathophysiologic mechanisms of the one-and-a-half syndrome and of the clinical findings recorded are discussed.<br>O autor relata o caso de um paciente de sexo masculino de 54 anos com hematoma pontino que se manifestou por síndrome "one-and-a-half" e ataxia cerebelar mas sem sinais de acometimento do trato piramidal. A ausência de acometimento do trato piramidal é decorrente possivelmente de uma variação da anatomia vascular do segmento pontino do tronco cerebral. Os achados clínicos do caso e os mecanismos fisiopatológicos da síndrome "one-and-a-half" são discutidos. |
