We present a case of lower back pain with lumbar nerve compromise due to a ligamentum flavum haematoma which was successfully treated surgically. A 62-year-old man was evaluated for lower back pain with associated leg pain and early signs of cauda equina syndrome. MRI of the lumbar spine demonstrated a contrast-enhancing mass adjacent to the lamina of L3 which was causing severe canal stenosis. Surgical excision of the lesion was recommended. The patient underwent an L3 laminectomy with excision of the epidural lesion. Histopathology showed it to be a haematoma of the ligamentum flavum with no untoward features. The patient recovered without complication.
