Intrathoracic Extramedullary Hematopoiesis

Radiology, 1964
Bone marrow production of the cellular elements of blood may be supplemented by foci of extramedullary hematopoiesis. This compensatory mechanism takes place when curtailed production or increased demand interferes with normal hematopoiesis. Extramedullary hematopoiesis has occurred in anemias associated with thalassemia, pernicious anemia, hereditary ...
