Calcification in untreated mediastinal Hodgkin's lymphoma.

Calcification is very rarely reported in untreated thoracic lymphoma. However, calcification can occur (although uncommonly) in lymphoma following chemotherapy or radiation, and in areas of scaring or fibrous healing. The authors describe the case of a pregnant woman with a large mediastinal mass that contained calcifications visible on both chest radiography and thoracic computed tomography, which proved to be Hodgkin's lymphoma.
