CTICasesPost-Radiation Hodgkin Lymphoma Calcification
Imaging findings
Chest radiograph and CT show dense, nodular calcification within treated Hodgkin's lymphoma tissue in the anterior mediastinum and diaphragmatic nodes. There is associated symmetric paramediastinal reticular fibrosis and hilar elevation.
Key takeaways
Densely calcified anterior mediastinal and diaphragmatic lymph nodes are characteristic late findings of treated Hodgkin's lymphoma. Diaphragmatic nodes were historical sites of recurrence due to cardiac shielding during radiotherapy.
