title: Traumatic sacral pseudomeningocele with spina bifida occulta.
abstract: Pseudomeningocele arises after spinal fracture and nerve root avulsion or after complications of spine surgery. However, traumatic pseudomeningocele with spina bifida occulta is rare. In this report, a traumatic pseudomeningocele in a patient with spina bifida occulta that required surgical treatment is documented. This 37-year-old man presented to the authors' hospital with headache and a fluctuant mass in the center of his buttocks. A CT scan with myelography and MR imaging of the sacral region revealed a large subcutaneous area of fluid retention communicating with the intradural space through a defect of the S-2 lamina. Because 3 months of conservative treatment was unsuccessful, a free fat graft was placed with fibrin glue to seal the closure of the defect, followed by 1 week of CSF drainage. This is the first report on traumatic pseudomeningocele with spina bifida occulta successfully treated in this manner.
