A case of extramedullary hemopoiesis in an 18-yr-old girl suffering fr
om beta-thalassemia is reported. Extramedullary hemopoietic masses wer
e localized apart from the paraspinal region in the retrocrural areas
as well as the presacral region associated with massive destruction of
the sacrum. The importance of recognition of hemopoietic masses in th
ese regions in conditions other than hereditary hemolytic anaemias is
briefly discussed.
