Periportal Extramedullary Hematopoiesis
topic hematopoiesis that is a common feature of chronic bone marrow failure. However, EMH is rarely encountered in general radiological practice (1). A mass-like EMH lesion in the liver is an atypical presentation. Furthermore, hepatic periportal EMH is less common than other types of focal hepatic EMH (2). We present the sonographic and CT findings of a histologically confirmed case of hepatic...
متن کاملExtramedullary hematopoiesis in renal allograft
Extramedullary hematopoiesis (EMH), defined as the presence of hematopoietic elements outside of the medullary cavity of bone, has been reported in patients with various hematopoietic neoplasms including myelofibrosis. EMH commonly occurs in the liver and spleen (resulting in hepatosplenomegaly) and uncommonly involves the kidney. EMH involving the allograft kidney has not been reported in Engl...
متن کاملHomeostatic and pathogenic extramedullary hematopoiesis
Extramedullary hematopoiesis (EH) is defined as hematopoiesis occurring in organs outside of the bone marrow; it occurs in diverse conditions, including fetal development, normal immune responses, and pathological circumstances. During fetal development, before formation of mature marrow, EH occurs in the yolk sac, fetal liver, and spleen. EH also occurs during active immune responses to pathog...
متن کاملIntracranial Extramedullary Hematopoiesis in Beta-Thalassemia
Extramedullary hematopoiesis (EMH) represents tumor-like proliferation of hemopoietic tissue which complicates chronic hemoglobinopathy. Intracranial EMH is an extremely rare occurrence. Magnetic resonance imaging (MRI) offers a precise diagnosis. It is essential to distinguish EMH from other extradural central nervous system tumors, because treatment and prognosis are totally different. Herein...
متن کاملExtramedullary Hematopoiesis in Abusive Head Trauma
Extensive unilateral extramedullary hematopoiesis of the choroid was observed in an otherwise clear cut case of abusive head trauma with bilateral retinal hemorrhage, optic nerve sheath hemorrhage and peripapillary intrascleral hemorrhage. Review of 60 archival cases of suspected abusive head trauma identified two more examples of extramedullary hematopoiesis in abusive head trauma that initial...
