Extramedullary hematopoiesis (EMH) refers to the location of hematopoietic elements in locations other than the bone marrow andperipheral blood. It may be seen as a compensatory condition in many hematological conditions like myeloproliferative disorders included myelofibrosis, haemoglobinopathies. 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, middle mediastinum and presacral region on computed tomography in a patient of myelofibrosis.
