[Eosinophilic bone granuloma in an 8-month-old infant]

A solitary eosinophilic granuloma in an 8 month-old infant is presented. The tumour, which had penetrated bone dura, but spared the brain tissue was radically excised. This case shows an unusually low age of presentation of this rare disease, and an unusual endocranial extension of the tumour. If an infantile eosinophilic granuloma is suspected, then computerized tomography should always be performed.
