Herein, we describe a 34-year-old male who presented with acute radiculopathy attributed to a small L4 ventral root schwannoma. Case Description: A 34-year-old male suddenly developed left leg pain. Magnetic resonance imaging (with/without contrast) revealed a small intradural mass lesion involving the L4 nerve root that was enhanced with contrast (size: 9 × 12 × 12 mm). The computed tomography myelogram revealed that the tumor had originated from the L4 ventral root and compressed the dorsal root in the lateral recess. Following a decompressive laminectomy for tumor removal, the patient’s radicular pain improved. The histological diagnosis was consistent with a schwannoma. Conclusion: Small cauda equina schwannomas involving ventral nerve roots can cause acute radiculopathy readily relieved with decompressive laminectomies for tumor excision.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/4e74932f-2430-420f-92ac-9efc272d7aab/featured/hero-1781562316937.png","publishDate":"2021-06-21T00:00:00.000Z","doi":"10.25259/SNI_438_2021","categories":["Spine","Case Report"],"fullTextUrl":"https://surgicalneurologyint.com/api/articles/4e74932f-2430-420f-92ac-9efc272d7aab/pdf"}
