A 3-year-old girl with stage III diffuse anaplastic Wilms tumor who has undergone nephrectomy, 6 weeks of chemotherapy, and whole abdomen/right hemithorax/flank irradiation develops new pulmonary nodules in the right upper lobe that are revealed on routine surveillance chest computed tomography (CT) scan (Figure).

Further clinical history obtained from the patient reveals a long history of pica and playing in the neighborhood sandbox. Laboratory values document hypereosinophilia and hypergammaglobulinemia. Imaging obtained 4 weeks later again identifies resolution of old nodules and evidence of new nodules (Figure). The migratory pattern of...
