Description
Summary:In a 52-year-old woman, spinal arteriovenous malformation (AVM) has been associated with what has been known as Foix-Alajouanine syndrome. The pathophysiology of the AV fistula is probably related to increased venous pressure from the AVM plus thrombotic process.The most common initial symptoms are sensory disturbance, pain and leg weakness. Definitive diagnosis of spinal AVMs requires radiographic demonstration of the vascular anomaly. Nevertheless, in this case, suggestive defects of malformations could not be seen, in contrast to the MRI findings and macroscopical and anatomical-pathological lesion. These findings rise our attention, about the need to keep in mind the clinical suspicion of AVM in cases of back pain and motor deficit, and an early surgical conduct in this situation.<br>Em mulher de 52 anos, malformação artério-venosa medular (MAV) associava-se com a síndrome de Foix-Alajouanine. A fisiopatologia da fístula artéria-venosa provavelmente está relacionada com a pressão venosa aumentada, a partir da MAV associada com o processo trombótico. Os sintomas iniciais mais comuns são distúrbio sensorial, dor e fraqueza do membro inferior. O diagnóstico definitivo de MAV medular requer evidências radiográficas da anomalia vascular. De qualquer modo, neste caso, defeitos sugestivos de malformações não foram detectados, contrastando com os achados de ressonância magnética e lesões macroscópicas e anátomo-patológicas. Estes resultados chamaram a atenção e excluíram outras causas. A alta suspeita clínica de MAV nos levou a uma conduta cirúrgica precoce em benefício do paciente.
