Wilms' tumor metastatic to the mediastinum.
We report two children with mediastinal metastasis of Wilm's tumor. One case presented with a right hilar mass and the other with a posterior mediastina mass. In each instance, no additional radiologic evidence of metastasis was found. Metastasis of Wilms' tumor to the mediastinum is uncommon, usually occurring with radiologic evidence of either additional metastases or direct cephalad growth of the primary tumor.
