Extra Modular Hematopoiesis: A Case Report Of Posterior Mediastinal Tumor With Minor Thalassemia

Nous presentons un cas d'hematopoiese extra­medullaire chez une fille de 16 ans. Cette fille etait attainte d'une thalassemie mineure. Le foyer d'hematopoiese extramedullaire se pre­sentait comme une masse tumorale dans le mediastin posterieur.

Extradural extramedullary hematopoiesis: a rare MRI diagnosis with atypical features.

Extra-medullary hematopoiesis occurring in spinal epidural space with resulting cord compression is rare. We report a case of extra-medullary hematopoiesis causing thoracic spinal cord compression in a patient of myelofibrosis. Because of atypical MRI findings, it posed a significant diagnostic challenge. Therefore, we have discussed MRI features of this rare complication in correlation with re...

Extra-medullary haematopoiesis: a pictorial review of its typical and atypical locations.

Extra-medullary haematopoiesis (EMH) occurs in many haematological disorders and is secondary to insufficient bone marrow function or ineffective erythropoiesis. It usually presents as haematopoietic masses in several typical and atypical body locations. This pictorial review briefly discusses the common EMH locations encountered in clinical practice, including the liver, spleen, lymph nodes an...
