Imaging findings
An incidental, enhancing lesion is noted in the anterior mediastinum, appearing to arise near the sternoclavicular joint or between the rib and sternum/manubrium. The MRI report described dramatic enhancement.
Key takeaways
This case illustrates hyaline vascular Castleman disease, a localized lymphoproliferative disorder. The location, initially attributed to the chest wall, was re-evaluated during discussion to be more consistent with an internal mammary lymph node, which is a common site for nodal involvement. Such lesions often show dramatic enhancement on imaging.
