Diagnostic imaging of intrathoracic extramedullary haematopoiesis

Abstract

Key message 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.
