Thymic and adenotonsillar enlargement after successful treatment of malignancies.

Anterior mediastinal and adenoid masses in children after cessation of chemotherapy for malignant disease often cause a diagnostic problem. Differential diagnosis of thymic enlargement and adenoid hyperplasia from recurrence frequently poses a challenge both for the radiologist and the physician. In this study the authors evaluated 491 patients with different malignant tumors for thymic and adenoid hyperplasia.
