In children, lymphomas and germ cell tumors are the most common and thymomas infrequent. MATERIALS AND METHODS: Twenty-seven cases of thymolipoma were reviewed. Clinical, radiologic, and pathologic findings were noted. RESULTS: The masses occurred in 15 male and 12 female patients (mean age, 26.7 years).

Sakai S, Murayama S, Soeda H, Matsuo Y, Ono M, Masuda K. Differential diagnosis between thymoma and non-thymoma by dynamic MR imaging. Differentiation of thymoma/non‐thymoma based on the peak time of dynamic MR imaging showed optimal sensitivity (79%) and specificity (84%) when defining thymomas as lesions having peak time appearing earlier than 2 min and non‐thymomas later than 2.5 min, with an accuracy of 81%.
