For vertebral fractures, cyphoplasty appears to be the most innocent treatment modality, but percutaneous injection of cyphoplasty cement might cause serious complications as the injection causes increased venous pressure in the paravertebral space. Here, we report a case of late-onset spinal subdural hemotoma after 6 h of percutaneous balloon cyphoplasty. A 58-year-old woman with an acute compression fracture of the second lumbar vertebrae underwent percutaneous balloon cyphoplasty. After 6 h, she had late-onset neurological deficits and leg pain. Emergent lumbar Mr was performed. The MR images revealed intraspinal hemotoma. The patient was operated, and spinal subdural hemotoma was removed. Spinal subdural or epidural hemotoma is believed to occur because of increased venous drainage pressure that leads to the rupture of venous vessels following cyphoplasty. These hematomas should be immediately removed, otherwise irreversible neurological complications may occur.
