Resumo

JUSTIFICATIVA E OBJETIVOS: Os cistos perineurais podem gerar dor com características neuropáticas de difícil controle. Os anticonvulsivantes são medicações utilizados para tratamento de dores com essas características. O objetivo deste relato é mostrar um caso com total remissão da dor com uso de gabapentina após o insucesso no tratamento com todas as outras alternativas terapêuticas utilizadas. RELATO DE CASO: Paciente de 67 anos, diabética, com queixa de dor lombossacra há dois meses, com as seguintes características: diária, em pontada e queimação, de intensidade leve a moderada e com irradiação para região posterior da coxa. Piorava com o movimento e com a posição ortostática. Há seis meses havia tido um episódio semelhante de dor, que melhorou com o uso de corticoesteróides. A ressonância nuclear magnética da coluna lombossacra mostrava lesões císticas perineurais sacrais em S1, S2 e S3 com diâmetro de 2,5 a 4 cm, comprimindo o saco dural associado à erosão óssea. Foi introduzida a gabapentina em doses progressivas até 900 mg/dia, com alívio completo do quadro álgico. CONCLUSÕES: A dor neuropática provocada pelo cisto de Tarlov pode ser controlada de maneira adequada com gabapentina.

Abstract

BACKGROUND AND OBJECTIVES: Perineural cysts may induce difficult to control neuropathic pain. Anticonvulsivants are used to treat such pain. This report aimed at presenting a case of total pain remission with gabapentin after failure of all other therapeutic alternatives used.
CASE REPORT: Female, diabetic patient, 67 years old, complaining of lumbosacral pain for two months, with the following characteristics: daily, sharp and burning pain of mild to moderate intensity irradiating to posterior thigh. Pain would worsen with movement and in the standing position. Six months before she had had a similar pain episode which improved with steroids. Lumbosacral spine MRI showed 2.5 cm sacral perineural cyst injuries at S1, S2 and S3, compressing the dural sac and associated to bone erosion. Gabapentin was introduced in progressive doses until 900 mg/day, with complete pain relief.
CONCLUSIONS: Tarlov's cyst neuropathic pain may be adequately controlled with gabapentin.
