Figure 10a. Lingual epidermoid carcinoma after Wilms tumor in a 15-year-old boy. The patient had been treated for Wilms tumor with pulmonary metastases at the age of 5 years. Axial T2-weighted (a) and contrast-enhanced T1-weighted (b) MR images demonstrate a hyperintense enhancing mass (arrow) that involves the middle and posterior thirds of the right side of the tongue. The tongue carcinoma was surgically resected, and radiation therapy was administered. Follow-up MR imaging performed 5 years later showed no tumor recurrence.
