Spinal Epidural Venous Angioma Presenting Symtomps of Lumbar Disc Herniation: A Case Report

Abstract

Spinal epidural venous angiomas are extremely rare. We report the case of a 60-year-old man who presented with disc herniation symptoms, complaining of pain in his left leg and numbness, especially at the base of the knee. On physical examination, the Lasègue test was positive at 45 degrees on the left side and no neurological deficit was detected on the lower extremity. Contrast enhanced magnetic resonance imaging revealed a lesion in the left S1 neural foramen, which was initially evaluated as a schwannoma. However, after the lesion was totally excised, it was pathologically identified as a venous angioma. Here, the clinical presentation, management, and surgical, radiological, and pathological features are discussed.
