title: Left-sided posterior mediastinal thymus--MRI findings.
abstract: Anomalous descent of the thymus may result in ectopic thymic tissue in the neck and/or the mediastinum and can mimic an abnormal mediastinal mass. We present one case of a "posterior mediastinal mass" that was diagnosed as a posterior mediastinal thymus utilizing CT plus MRI.
