Number 08-22: A Segmented thoracic mass
Case from: Ferdinando Pasquale, Maciej Garbowski, John Porter, Mark Westwood. Departments of Cardiology and Haematology The Heart Hospital and UCLH, London UK
History: A 32 yrs old man was referred for assessment of iron loading by measurement of cardiac T2*. Past medical history of transfusion dependent thalassaemia (thalassemia) major and chronic iron chelation therapy.
Interpretation: This is the classical appearance of thoracic paravertebral extramedullary hematopoiesis. The classical segmental striping is seen in this case. Other mediastinal masses can be striped (eg massive confluent lymphadenopathy in Hodgkins). Extramedullary hemopoiesis is less common now in many parts of the world due to blood transfusions. Rarely, this tumor-like mass can cause spinal cord compression requiring radiotherapy or surgical removal.
