Figure 2.
Contrast-enhanced CT chest imaging demonstrating soft tissue in the anterior mediastinum with a triangular configuration measuring 39 Hounsfield units. This spans a cross-sectional area of approximately 2.5 cm × 2.0 cm over a craniocaudal distance of 4 cm. This is consistent with residual or hyperplastic thymic tissue in a patient of this age. CT, computed tomography.
