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.
