Para-vertebral extramedullary hematopoiesis (PVEH) is defined as an ectopic development of hematopoietic tissue outside the bone marrow. It is a very rare condition, secondary to haematological disorders leading to chronic anemia. The present report describes two cases of chronic anemia patients with paraspinal medullary hematopoiesis and analyzes the clinical manifestations, imaging, pathology, diagnosis and treatment of EMH. In addition, a supplementary review of previously published cases is provided along with a review of the related literature. Computed tomography (CT) of the first case revealed paraspinal masses, and the largest was 6.2x8.0 cm in diameter. Likewise, MIRy of the second patient revealed multiple paraspinal masses in the bottom of the left thoracic cavity, and the largest was measured 10.1x10.5 cm. In conclusion, EMH is a compatible and rare disease, and should be distinguished from other neoplasms.
