Unusual CNS presentation of neuroblastoma.

Neuroblastoma is a common tumor of childhood, usually occurring in children under 4 years of age [1]. We report a case of a 10-year old child who initially presented with a large calvarial mass representing a solitary site of metastasis from an occult adrenal neuroblastoma. The sunburst pattern of the calvarial metastasis noted in this case is rarely seen with neuroblastoma. The age of our patient, solitary focus of metastasis at presentation, and imaging appearance of the tumor are very uncommon findings of neuroblastoma.
