"Lung metastases are common. The incidence of synchronous lung metastasis at initial cancer presentation is approximately 18 per 100,000 population, noting that this figure does not include metachronous metastases (occurring after initial cancer staging) 8. Around 4% of all cancer cases present with synchronous lung metastases 8. "

"In adolescents aged 10 to 20, bone and soft tissue sarcomas are the major sources in both sexes 8. Under age 10, kidney and soft tissue tumours dominate 8. The most common primaries for paediatric pulmonary metastases are the following histologies:"

"Calcification, although uncommon and more frequently a feature of benign aetiology (e.g. granuloma or hamartoma), is also seen with metastases, particularly those from papillary thyroid carcinoma and adenocarcinomas. Treated metastases, osteosarcomas and chondrosarcomas may also contain calcified densities 1."
"Pulmonary metastases typically appear as multiple, peripheral, rounded nodules scattered throughout both lungs 1. Larger nodules and masses may be termed cannonball metastases. Atypical features include consolidation, cavitation, cystic change, calcification, ossification, haemorrhage, and secondary pneumothorax."
