Extramedullary haematopoiesis - thalassaemia

Case contributed by Dr Andrew Dixon


Chest pain and left sided pleural effusion.

Patient Data

Age: 50
Gender: Male

Diffusely expanded bones. Mutiple well-defined posterior mediastinal / paravertebral soft-tissue density masses. Patchy left lower lobe consolidation and small left pleural effusion. 

Case Discussion

There is marked medullary expansion of all bones suggesting that the multiple posterior mediastinal masses represent extramedullary haematopoiesis. This patient had known thalassaemia as the cause. The region of consolidation in the left lower lobe and left pleural effusion most likely account for the patient's chest pain.
