Extramedullary hematopoiesis
From Wikipedia, the free encyclopedia
Extramedullary hematopoiesis refers to hematopoiesis occurring outside of the medulla of the bone.
In some cases, it may be physiologic. For example, during fetal development, hematopoiesis occurs at many different locations, such as the liver and spleen.[1]
However, it is more frequently associated with pathologic processes. For example, it can be caused by myelofibrosis.[2]
It can sometimes be identified via computed tomography.[3]
