Core Tip
Core Tip: Ligamentum flavum cyst in lumbar spine can be a rare cause of spinal stenosis. There have been several case reports of ligamentum flavum cysts. However, to the best of our knowledge, no calcified ligamentum flavum cyst has been reported. We report the first case of a calcified ligamentum flavum cyst causing neurological claudication and motor weakness of lower extremities. We believe that our report would be useful for a diagnostic approach and treatment in patients who have spinal stenosis with neurological claudication and motor weakness.
