Abstract

Although intrathoracic extramedullary haematopoiesis (EMH) is rare, its nodular lesions should be differentiated from malignancy. ¹¹¹In-bone marrow scintigraphy can be useful for the non-invasive diagnosis of intrathoracic EMH because extramedullary accumulation of ¹¹¹In can be determined as EMH.

Keywords: bone marrow scintigraphy; extramedullary haematopoiesis; pleural nodules; pulmonary nodules.
