Barbosa ABR et al. / Schwannoma <strong>do</strong> <strong>hipoglosso</strong>: relato de caso<br />
CONCLUSÃO<br />
Os <strong>schwannoma</strong>s <strong>do</strong> <strong>hipoglosso</strong> são infreqüentes e<br />
devem ser considera<strong>do</strong>s como causa de paralisia <strong>do</strong> 12º<br />
nervo craniano. A RM é excelente arma para a confirmação<br />
diagnóstica, nos diagnósticos diferenciais e no<br />
planejamento cirúrgico, pois demonstra a exata extensão<br />
da massa, a localização anatômica precisa e as relações<br />
com as estruturas adjacentes [2,7,8,9] .<br />
