Treated Hodgkin Lymphoma


General Considerations

  • In the chest, Hodgkin lymphoma most often involves the mediastinum, especially the anterior mediastinal nodes
  • External beam radiation therapy and/or chemotherapy are common treatments for the disease
  • Calcification of mediastinal nodes previously involved with Hodgkin lymphoma occurs in 2-8% of those treated with either previous radiation therapy or chemotherapy
  • It usually occurs at least 8 months after treatment, but has been reported later
  • Most reported patients with calcification in Hodgkin's lymphoma had the nodular sclerosing type
  • It is presumed the calcification is a result of cellular necrosis, hemorrhage and fibrosis in degenerating tumor

Imaging Findings

  • It is very rare for lymph nodes to be calcified pre-treatment in Hodgkin lymphoma
  • Calcification can either be punctate or become coalescent and dense

Differential Diagnosis

  • TB
  • Silicosis
  • Histoplasmosis
  • Coccidioidomycosis


  • There is a suggestion that post-treatment nodal calcification is associated with a better prognosis


Hodgkin Lymphoma, treated

Hodgkin Lymphoma, treated. Unenhanced axial and sagittal images of a chest CT scan show numerous, punctate calcifications in the anterior mediastinum representing calcified, lymph nodes in a patient treated with radiation therapy for Hodgkin Disease 6 years earlier.
