A Cervical Epidural Hematoma Caused by Ruptured Arteriovenous Malformation Presenting as a Brown-Sequard and Horner's Syndrome - A Case Report -

Brown-Sequard 증후군과 Horner씨 증후군으로 발현된 동정맥 기형 파열로 인한 경추 경막외 혈종 - 증례보고 -

We report a rare case of Brown-Sequard syndrome associated with Horner's syndrome in cervical epidural hematoma caused by a ruptured arteriovenous malformation. A 54-year-old man developed sudden sharp neck pain, radiating to the interscapular area. Within hours, left side hemiplegia and decreased tactile sense and loss of contralateral pain sense ensued. Emergency cervical magnetic resonance image showed an epidural hematoma over the cervico-thoracic junction. The hematoma was located in the left posterolateral area of the cervical spinal canal. Emergent decompressive laminectomy and an evacuation of the hematoma were performed. A tangled soft tissue mass found in the hematoma was proven to be an arteriovenous malformation. To the authors, knowledge, this might be the first case of a Brown-Sequard syndrome associated with Horner's syndrome caused by ruptured cervical epidural arteriovenous malformation.
