title: Long-term neurological sequelae in achondroplasia.
abstract: Two children with achondroplasia and neurologic sequelae secondary to foramen magnum compression were found to have syringomyelia. In one patient, the cyst was associated with a subependymal glioma. These findings suggest that foramen magnum stenosis may lead to irreversible spinal cord damage.
