Abstract
Cystic masses are generally congenital and arise anywhere in the mediastinum, and MRI is useful to confirm their cystic nature, especially in the cysts with soft tissue attenuation at CT. In the thymus, chemical-shift MRI can characterize the normal thymus and thymic hyperplasia by detecting tiny amounts of fat tissue within the thymus and differentiate such benign processes from thymic tumors. Malignant lymphoma is a relatively common disease in the mediastinum, and MRI provides important information, especially in the assessment of viability of residual masses in treated lymphoma. In the diagnosis of neurogenic tumors, MRI can precisely evaluate shape, location, intraspinal extension, and internal components of the tumors.
