Resumos

Foi avaliada por ressonância nuclear magnética a incidência de malformações da medula espinal em 38 crianças com espinha bífida. Destas, 22 apresentavam espinha bífida aberta e 16 espinha bífida oculta. Medula presa foi detectada na maioria dos pacientes. Siringomielia foi encontrada em 13 casos. A transição occipitocervical foi estudada em 11 pacientes com meningomielocele e malformação de Chiari foi encontrada em 8. A análise da casuística permitiu comprovar que existe número significativo de malformações assintomáticas detectadas pela RNM.

We studied by magnetic resonance imaging the incidence of associated malformations in a group of 38 patients with diagnosis of spina bifida followed in our outpatient clinic. Twenty-two children were born with spina aperta and 16 with spina bifida occulta. Tethered cord was found in the majority of patients of both groups. Syringomyelia was found in 13 patients. The craniocervical region was studied in 11 patients with diagnosis of spina bifida aperta; Chiari malformation was found in 8. The results point to the fact that asymptomatic malformations detected by MRI techniques are frequent in patients with spina bifida.

SUMMARY

We studied by magnetic resonance imaging the incidence of associated malformations in a group of 38 patients with diagnosis of spina bifida followed in our outpatient clinic. Twenty-two children were born with spina aperta and 16 with spina bifida occulta. Tethered cord was found in the majority of patients of both groups. Syringomyelia was found in 13 patients. The craniocervical region was studied in 11 patients with diagnosis of spina bifida aperta; Chiari malformation was found in 8. The results point to the fact that asymptomatic malformations detected by MRI techniques are frequent in patients with spina bifida.

Key words: spinal cord, malformation, spina bifida, magnetic resonance imaging.
