Presacral and intrathoracic extramedullary hematopoiesis: a case report

Published:November 23, 2011DOI:https://doi.org/10.1016/j.clinimag.2011.10.017

      Abstract

      Extramedullary hematopoiesis (EMH) refers to the location of hematopoietic elements in locations other than the bone marrow and peripheral blood. It may be seen as a compensatory condition in many hematological conditions including thalassemia, or it may occur as an incidental finding. Intrathoracic EMH commonly develops in the posteroinferior mediastinum. Presacral EMH is an extremely rare condition, and there are a limited number of case reports published in the literature. We are reporting a case of EMH that involves the posterior mediastinum and presacral region on computed tomography and magnetic resonance imaging in a patient with thalassemia intermedia.
