Extramedullary plasmacytomas are plasma cell tumors that arise outside the bone marrow. They are most often located in the head and neck. Extramedullary plasmacytomas account for approximately 3 percent of plasma cell malignancies. The diagnosis of an extramedullary plasmacytoma depends upon the demonstration of a monoclonal plasma cell tumor at an extramedullary site with no evidence of multip...
متن کاملCord Compression due to Extramedullary Hematopoiesis in an Adolescent with Known Beta Thalassemia Major.
We describe a 16 year-old male with β thalassemia major and gait disturbances that had not been given blood transfusions due to a severe childhood transfusion reaction. Thoracic spine MRI demonstrated hematopoietic marrow throughout the spine and epidural masses causing cord compression consistent with extramedullary hematopoiesis (EMH). After treatment with steroids, radiotherapy and monitored...
متن کاملCompressive Optic Neuropathy in Thalassemia: A Rare Ophthalmic Consequence of Extramedullary Hematopoiesis
Extramedullary hematopoiesis (EMH) is a compensatory physiological proliferation of hematopoietic elements outside the bone marrow as a result of insufficient bone marrow erythropoiesis. It is found in various hematologic disorders (e.g., as sickle cell anemia, thalassemia, myelofibrosis) especially those with chronic anemias. It can affect in any organs, thus producing numerous complications. ...
متن کاملPET CT imaging in extramedullary hematopoiesis and lung cancer surprise in a case with thalassemia intermedia Talasemi intermedia olgusunda ekstramedüller hematopoezin PET CT görüntülemesi ve akciğer kanseri sürprizi
Extramedullary hematopoiesis (EMH) is the production of hematopoietic precursors outside the bone marrow cavity, and it causes mass effects according to its localization. Magnetic resonance imaging (MRI) and/or computed tomography (CT) scans are used most commonly to detect EMH foci. We report herein a case with thalassemia intermedia causing paravertebral mass associated with EMH detected by C...
متن کاملParanasal sinus involvement in thalassemia major: CT demonstration.
Beta thalassemia is a blood dyscrasia caused by defective synthesis of the beta chain of hemoglobin. This causes severe anemia due to ineffective erythropoiesis and peripheral hemolysis of the defective red cells . Marked expansion of active marrow spaces and extramedullary hematopoiesis result. Classic radiographic findings of thalassemia, in particular the hair-on-end appearance in the skull ...
