Craniocerebral neuroblastoma metastases usually involve the calvaria, orbits, skull base and the dura.

Radiographic features:

CT:

• spiculated periorbital bone mass, typically involving the roof or lateral wall/sphenoid wings
• "hair on end" spiculated periostitis of orbits and skull usually associated with bone destruction
• sutural separation: non-uniform sutural separation with indistinct sutures margins
• cranial metastasis nearly always extradural (may mimic epidural or subdural hematoma)
