A primary thoracic origin occurs only in 20% of neuroblastomas, and their classical presentation is mediastinal or cord compression. Skeletal metastases of neuroblastomas are characteristically multiple, and calvarial deposits usually show simultaneous involvement of orbit. Solitary metastases in neuroblastoma, is an unusual entity and its presentation as a large calvarial mass, especially from a thoracic primary, is rare. Furthermore, calvarial metastases are relatively uncommon in children compared to adults. We discuss the clinical, radiographic, CT features, and differential diagnosis of a large calvarial mass with sunray spiculation in a child, which was due to a solitary metastases from an occult thoracic neuroblastoma. The possibility of neuroblastoma presenting in this unique fashion and the importance of considering a chemosensitive tumor such as neuroblastoma in the differential diagnosis of a solitary calvarial mass in a child is highlighted by our report.
