    Abstract:
    Von Recklinghausen's disease associated with hydrocephalus due to non-tumoral aqueductal stenosis is rare. Furthermore the formation of subdural hematoma within the spinal canal is also a very rare complication of ventriculoperitoneal shunt. We presented a case of spinal subdural hematoma formation following ventriculoperitoneal shunting for von Recklinghausen's disease associated with aqueductal stenosis. A 10-year-old girl with von Recklinghausen's disease was referred to our hospital for gait disturbance during the previous 8 months. Magnetic resonance imaging (MRI) revealed hydrocephalus due to non-tumoral aqueductal stenosis, and ventriculoperitoneal shunt was instituted. Three months later, the patient developed lumbar pain and paraplegia. MRI revealed subdural hematoma in the lumbosacral spinal canal, and bilateral intracranial subdural hematoma were shown on computerized tomography (CT) scans. Subdural hematoma in the lumbosacral spinal canal was evacuated by laminectomy. Improvement of her neurological deficit was obtained postoperatively, and intracranial subdural hematomas disappeared spontaneously. Spinal subdural hematoma is assumed to be formed by the migratory movement of intracranial subdural hematoma under the influence of gravity. A characteristic finding of MRI is that such a subdural hematoma in the lumbosacral canal is located around the cauda equina.
