Pulmonary blastoma: radiologic findings in five patients.
OBJECTIVE
To determine the radiologic findings of pulmonary blastoma on chest radiograph and CT.


METHODS
Chest radiographs and CT scans of five patients with pathologically proven pulmonary blastoma were retrospectively evaluated and radiologic findings were correlated with histopathologic findings.


RESULTS
On chest radiograph, the pulmonary blastoma manifested as a solitary parenchymal mass (n = 2), a solitary parenchymal nodule (n = 1), hilar bulging with fingerlike parenchymal opacities (n = 1), or opacification of hemithorax (n = 1). On CT, the pulmonary blastoma manifested as a solitary parenchymal mass (n = 2), a solitary parenchymal nodule (n = 1), an endobronchial mass with postobstructive pneumonitis (n = 1), or a parenchymal mass with multiple subpleural masses and pleural effusion (n = 1).


CONCLUSIONS
Pulmonary blastomas most commonly manifested as a solitary parenchymal mass on chest radiograph and CT. These radiologic features are nonspecific and many primary or metastatic tumors of the lung could be included in differential diagnosis.
