Abstract
Cysts of the ligamentum flavum, also known as “flaval cysts”, are benign fluid collections developed within the layers of the ligamentum flavum (yellow ligament). Most cases grow into the anterolateral spinal epidural space and may compress the neural elements and result in a neurological disturbance in many patients. In the lumbar region, a considerable number of cases will manifest as unilateral or bilateral sciatica. However, some cases remain asymptomatic.
