<unk>  refers to an enlargement ("hyperplasia") of the<unk> . It is not always a disease state. The size of the<unk>  usually peaks during adolescence and atrophies in the following decades. Before the immune function of the<unk>  was well understood, the enlargement was sometimes seen as a cause for alarm, and justification for surgical reduction. This approach is much less common today. It can be associated with myasthenia gravis. Magnetic Resonance Imaging can be used to distinguish it from thymoma.
