Ligamentum flavum cysts are rare causes of neurological signs and symptoms and usually seen in persons over 45 years of age. We report the case of a right-sided ligamentum flavum cyst occurring at L5–S1 level in a 60 year-old woman, which was surgically removed with excellent postoperative results, and complete resolution of symptoms. Lumbar magnetic resonance imaging demonstrated an extradural cystic mass at the L5-S1 intervertebral space and disc hernia with canal stenosis at the L4-5 intervertebral space. Right hemilaminectomy and flavectomy at the L4-5 and L5-S1 space were performed, and cystic mass with sequestered disc was excised. Histological examination of the resected material showed findings consistent with the ligamentum flavum cyst. After surgery, claudication and radiculopaty completely disappeared and the patient made a good recovery.
