Lung CT for detection of metastases: solid tissue neoplasms in children.

The results of 73 computed tomographic studies of lung and pleura in 52 children with solid-tissue tumors have been analyzed. In nine children computed tomography provided information not evident by chest radiograph or whole lung tomography. In four of these cases computed tomography demonstrated lung nodules not seen on chest radiography or whole lung tomography; in another four cases it revealed pleural involvement with tumor; and in one case it revealed calcium in a nodule. In two children computed tomography missed lung mestastases seen by lung tomography and chest radiography.
