ABSTRACT
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.

Gastric volvulus is a rare abdominal emergency in children and occurs secondary to associated predisposing congenital defects. The less frequent idiopathic variety of gastric volvulus is mostly chronic in its clinical course. Acute idiopathic mesenteroaxial gastric volvulus is a rare subtype and two out of the four reported cases of this entity among children in the past 12 years have been from the Indian subcontinent. We report another case of acute idiopathic mesenteroaxial gastric volvulus in a 7 year old Indian girl. Possibly there is an increased propensity of Asians to this is potentially fatal disease.

During childhood the common anterior middle mediastinal masses are either lymph node enlargement or teratomas/dermoids. A case of ossific mediastinal metastasis and pleural metastases from osteosarcoma, presenting three years after the primary disease (late metastasis) is reported for its rarity.
