Abstract

|
An 83-year-old female complained of intractable right buttock pain and anterior thigh pain after a fall. Magnetic resonance (MR) images revealed an acute osteoporotic compression fracture of the L1 vertebral body with the intravertebral cleft filled with fluid. MR image and MR myelography demonstrated epidural fluid collection causing compression of the cauda equina at the level of the L1 vertebral body, which originated from the intravertebral fluid at the L1 vertebral body. She underwent hemilaminectomy and drainage of epidural fluid, followed by percutaneous vertebroplasty at the L1 vertebral body. Her pain was relieved immediately after the operation. Epidural fluid collection which originated from avascular osteonecrosis associated with an osteoporotic vertebral compression fracture could be a cause of intractable pain in the buttock and the leg, as observed in the present case.
