Cranio-cerebral erosion: delayed diagnosis and treatment

Cranio-cerebral erosion is a well-known complication of calvarian fracture with underlying dural tear and cerebral injury in infancy and early childhood. The anatomy, pathogenesis and natural evolution of these lesions remain obscure. The common clinical symptoms are seizures, focal neurological deficits, impairment of consciousness and a soft subgaleal mass. Three patients of cranio-cerebral erosion who underwent delayed surgery in their adult lives are presented to illustrate the common and uncommon features, and their long-term outcome is discussed.
