Abstract
PURPOSE: To determine the radiologic findings of pulmonary blastoma on chest radiograph and CT. MATERIALS AND 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). CONCLUSION: 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.
