Thoracic involvement is less common and manifests as the presence of lobulated masses adjacent to the spinal column. A focus of immature hematopoietic cells (arrow) is present at the corticomedullary junction. By sharing our collective experience through interesting patient cases, we can make a real difference in how people are imaged and diagnosed. Red arrows point to pre-sacral and paravertebral extramedullary hematopoiesis.

However, in the less common situation where extramedullary haematopoiesis involves other tissues within the thorax, they can be seen as a posterior mediastinal mass. Response to insufficient blood cell production by production of blood elements outside of the marrow cavity, Most often due to hemolytic anemias such as sickle cell anemia, thalassemia and hereditary spherocytosis, May also be seen in prolonged iron deficiency anemia, myelofibrosis and sclerosis, polycythemia, leukemia and lymphoma, About a quarter of patients have no known hematologic disease, Areas of extramedullary hematopoiesis include the spleen, paraspinal regions of the thorax, liver and sometimes adrenals, bowel, dura mater and breast, Thalassemia is an inherited autosomal recessive blood dyscrasia resulting in underproduction of globins which may lead to severe anemia, Most often microscopic and asymptomatic, Bilateral paraspinal masses with round, lobulated margins, Thoracic masses occur most often in patients with thalassemia or congenital hemolytic anemia, Medullary expansion of the bony structures with widening of the ribs being the most pronounced bony finding, Resorption of trabeculae produces coarsened appearance to bones, Masses to don’t calcify and do not usually cause bone erosion, The lesions are usually of low-attenuation on non-contrast CT and may mildly enhance after contrast, Hydroxyurea reported to decrease the size of the masses.
