SUMMARY

In patients with cervical spondylotic myelopathy MRI sometimes shows increased signal intensity zones on the T2-weighted images. It has been suggested that these findings carry prognostic significance. We studied 56 subjects with cervical spinal cord compression. Twelve patients showed an increased signal intensity (21.4%) and a prevalence of narrowing of the AP-diameter (62% vs 24%). Furthemore, in this group, there was evidence of a longer mean duration of the symptoms and, in most of the patients, of more serious clinical conditions. The importance of these predisposing factors remains, however, to be clarified since they are also present in some patients without the increased signal intensity.

Key words: magnetic resonance imaging, cervical spondylotic myelopathy.


RESUMO

Em pacientes com mielopatia cervical espondilótica a ressonância magnética (RMN) às vezes mostra algumas zonas com sinal de maior intensidade nas imagens em T2, que teriam significado prognóstico. Examinamos 56 pacientes com compressão da medula cervical. Em 12 havia hiperintensidade (21,4%) e maior incidência de estreitamento do diâmetro ântero-posterior (62% contra 24%). Ainda, neste grupo se verificava duração média maior da sintomatologia e, na maior parte dos pacientes, sinais clínicos mais graves. Todavia, a importância desses fatores deve ainda ser esclarecida, pois estão presentes também em alguns pacientes que não apresentam a hiperintensidade.

Palavras-chave: ressonância magnética, mielopatia cervical espondilótica.
