title: Unusual non-metastatic nodules in the lungs of children with cancer.
abstract: The recognition of unusual non-metastatic causes of lung nodules in children with cancer is important. Appropriate therapy depends on an accurate diagnosis. Four patients are presented with lung nodules due to round pneumonia, round atelectasis, radiation pneumonitis and inflammatory pseudotumour. Clinical and radiographic features of these disorders are discussed. Awareness of these uncommon nodules is important if they are to be diagnosed accurately.
