Abstract
STUDY DESIGN: A patient with sciatica resulting from a hemorrhagic cyst of the ligamentum flavum is reported. Surgical removal of the cyst relieved the patient of her sciatic symptoms. SUMMARY OF BACKGROUND DATA: Cyst of ligamentum flavum is an uncommon cause of radiculopathy. There are 13 cases in the literature. CONCLUSIONS: The differential diagnosis of benign interspinal extradural mass lesions includes spinal synovial cysts, ligamentum flavum cysts, perineural cysts, dermoid cysts, and parasitic cysts.
