Here, we present a patient with an L1–L2 IDH and reviewed the current literature. Case Description: A 65-year-old female presented with the acute onset of bilateral paraparesis accompanied by urinary dysfunction. The lumbar MRI showed a mass at the L1–L2 level with caudal migration, accompanied by a positive “hawk-beak” sign. At surgery, consisting of a L1–L2 laminectomy, a large IDH was encountered responsible for marked cauda equina/root compression. Postoperatively, the patient immediately fully recovered. The literature we identified cited just seven similar studies of L1–L2 IDH. Conclusion: In a 65-year-old female, an IDH was anticipated at the L1–L2 level due to the combined MR findings of a large L1–L2 mass with caudal migration and the positive “hawk-beak” sign.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/60cb9f16-f5c0-45c6-81ec-85281ee398f1/featured/hero-1781563532795.png","publishDate":"2020-04-11T00:00:00.000Z","doi":"10.25259/SNI_108_2020","categories":["Spine","Case Report"],"fullTextUrl":"https://surgicalneurologyint.com/wp-content/uploads/2020/04/9954/SNI-11-67.pdf"}
