“…1,2 Extramedullary hematopoiesis (EMH) refers to an abnormal condition in which the bone marrow is not able to maintain adequate hematopoietic function, and hence, other locations in the body start compensatory hematopoiesis. 3 Decreased or ineffective marrow hematopoiesis results from various pathologic conditions such as anemia and hemoglobinopathies [eg, severe hypochromic anemia, pernicious anemia, megaloblastic anemia, thalassemia (Figs. 1-4), sickle cell disease (Fig.…”

“…6 Chronic anemia-induced marrow hyperplasia in thalassemia results in some characteristic changes in the skeletal system, such as thinning of the cortical bone, medulla expansion, resorption of the cancellous bone, and generalized osteopenia (Figs. 1,3,4). 7 In over 85% of patients with EMH, liver, spleen, and lymph nodes serve as the secondary sites of the hematopoiesis, followed by the paraspinal space in 5% of patients and the retroperitoneum in less than 2% of patients.…”

Radiology errors have been reported in up to 30% of cases when patients have abnormal imaging findings. Although more than half of errors are failures to detect critical findings, over 40% of errors are when findings are recognized but the correct diagnosis or interpretation is not made. One common source of error is when imaging findings from one process simulate imaging findings from another process but the correct diagnosis is not made. This can result in additional imaging studies, unnecessary biopsies, or surgery. Extramedullary hematopoiesis is one of those uncommon disease processes that can produce many imaging findings that may lead to misdiagnosis. The objective of this article is to review the common and uncommon imaging features of extramedullary hematopoiesis while presenting a series of interesting relevant illustrative cases with emphasis on CT.
