Age-stratified Patterns of Thymic Involution on Multidetector CT

Abstract

Residual thymic tissue in adults on MDCT is both more prevalent and more prominent than that reported in earlier studies and can be visible into the seventh decade. We recommend that radiologists and clinicians familiarize themselves with the normal range appearances of the thymus on MDCT, in order to prevent misinterpretation of normal thymic tissue as pathology, which may result in unnecessary procedures.
