Normal Distribution of 111In-chloride on Scintigram

Diagnostic imaging of intrathoracic extramedullary haematopoiesis

“…On CT images, pleural lesions of EMH typically form bilateral and multiple masses that have a sharp interface with the lung, especially in the paraspinal location; however, lung lesions of EMH can also present as nonspecific findings 1 . 111 In is transported to haematopoietic tissues by transferrin; therefore, extramedullary accumulation of 111 In can be determined as EMH 2 . Intrathoracic EMH has a high risk of haemorrhage during biopsy.…”

“… 1 111 In is transported to haematopoietic tissues by transferrin; therefore, extramedullary accumulation of 111 In can be determined as EMH. 2 Intrathoracic EMH has a high risk of haemorrhage during biopsy. Therefore, bone marrow scintigraphy should be performed in cases of suspected EMH before needle biopsy or thoracoscopic surgery.…”
