However, when they occur and contribute to epidural cauda equina compression, timely surgical intervention is frequently warranted.<\/jats:p>\n<\/jats:sec>\n\nCase Description: <\/jats:title>\nA 69-year-old female presented with the left lower extremity sciatica and gait disturbance of 2 weeks\u2019 duration that ultimately evolved into a paraparesis\/cauda equina syndrome. When the lumbar MRI revealed left-sided L4-L5 epidural compression attributed to a hemorrhage into the hypertrophied ligamentum flavum (HLF), she successfully underwent a bilateral fenestration\/decompressive procedure. Pathologically, neovascularization and rupture of the ventral layers of the degenerated and thickened HLF contributed to the LFH.<\/jats:p>\n<\/jats:sec>\n\nConclusion: <\/jats:title>\nArterial neovascularization (i.e., arterial feeding vessels from paramuscular\/prelaminar lumbar branches) contributed to a left-sided L4-L5 LFH that resulted in epidural cauda equina compression in a 69-year-old female.
