CTICasesHyaline Vascular Castleman Disease (Internal Mammary Lymph Node)
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.
