Resumo

A ciática é uma condição comum causada principalmente por compressão radicular; no entanto, casos raros de tumores do nervo ciático têm sido descritos como causa de dor ciática persistente sem explicação clínica clara. Relatamos aqui um caso raro de schwannoma do nervo ciático em um homem de 31 anos, que apresentou dor intensa no quadril esquerdo e apresentou resolução satisfatória dos sintomas após a ressecção cirúrgica do tumor. Neste caso, as imagens de ressonância magnética foram cruciais no diagnóstico diferencial entre schwannoma e neurofibroma, bem como para o planejamento e o sucesso do tratamento cirúrgico.

Abstract

Sciatica is a common condition caused mainly by radicular compression; however, rare cases of sciatic nerve tumors have been described as a cause of persistent sciatic pain with no clear clinical explanation. Here we report a rare case of sciatic nerve schwannoma in a 31-year-old man, presented with severe pain in the left hip, who had satisfactory resolution of symptoms after surgical resection of the tumor. In this case MRI images were crucial in the differential diagnosis between schwannoma and neurofibroma, as well as for the planning and success of surgical treatment.
