Post-traumatic cauda equina nerve calcification: A case report

This case report describes an extremely rare condition where calcium deposits form on the nerves of the cauda equina (the bundle of nerves at the base of the spinal cord) following a traumatic injury. The patient, a 52-year-old female, had a history of lumbar spinal stenosis and a lumbar vertebral fracture caused by trauma, which led to weakness and sensory loss in her right lower limb. Computed tomography (CT) scans revealed calcification of the cauda equina nerve. The patient was treated with a combination of traditional Chinese and Western medicine, including medication to reduce swelling and pain, as well as physical therapy to improve blood circulation. The patient's symptoms were slightly relieved after treatment.
