Magnetic resonance imaging of the lumbar spine showed a heterogeneous intensity mass in the lateral recess of the spinal canal at the L4-5 disk level. Postoperatively, her radicular pain resolved within a few days with excellent low back pain relief. Ligamentum flavum hematoma is a rare differential diagnosis for cystic lesions in the lumbar spine that can be removed simply by surgery with excellent relief of symptoms and improvement in strength of the right lower extremity and increased sensitivity.
