Pulmonary blastoma: a rare case of childhood malignancy

A case of pulmonary blastoma is presented with review of the radiographic, ultrasonographic and CT appearances of this rare malignant tumor of children. Pulmonary blastoma arises from primitive lung mesenchyma and histologically resembles fetal lung. The clinical presentation is usually respiratory distress. The prognosis of the disease is poor even if surgical resection, supplemental chemotherapy and radiation therapy are performed. We present a case of pulmonary blastoma who died two days after surgical resection.
