spinal cord compression due to extramedullary hematopoiesis is a well-described and rare syndrome encountered in several hematological disorders including β-thalassemia. hereby, a 37-year old pregnant woman with intermediate β -thalassemia with paraparesis and lower limb hypoesthesia was presented. mri showed soft tissue masses in both sides of thoracic paraspinal area. histologically, a mixtur...

AIMS To investigate the immunohistochemical expression of CD31 (JC70) in normal and neoplastic plasma cells. METHODS Plasma cells in bone marrow biopsies and extramedullary locations were examined. All extramedullary biopsies were formalin fixed and paraffin embedded. The bone marrow biopsies were fixed in formal acetic acid and embedded in paraffin wax. Twenty multiple myelomas (12 bone marr...

Extramedullary plasmacytoma (EMP) is a rare neoplasm of soft tissue which usually arises in the respiratory tract, nasal cavity, sinuses and nasopharynx. Multiple extramedullary plasmacytomas are extremely rare, especially those that are not associated with multiple myeloma.We describe multiple primary EMP in a 37 year old man, without involvement of bone or bone marrow. EMP usually has a ...

Myeloid sarcoma in acute myeloid leukemia has been clearly defined by the World Health Organization but studies regarding the prevalence and the prognostic impact of extramedullary acute myeloid leukemia have not been conducted. We performed (18)Fluoro-deoxy-Glucose Positron Emission Tomography/Computed Tomography scans in 10 patients with de novo and relapsed acute myeloid leukemia and histolo...

Background. Extramedullary hematopoiesis is most often seen in reticuloendothelial organs specially spleen, liver, or lymph nodes, and it is rarely seen in lung parenchyma. Almost all reported cases of pulmonary extramedullary hematopoiesis occurred following myeloproliferative disorders specially myelofibrosis. Other less common underlying causes are thalassemia syndromes and other hemoglobino...

Extramedullary hematopoietic effusion (EHE) is one of the extremely rare phenomena associated with extramedullary hematopoiesis, which caused by serous effusions, including pleural effusion, and may be related to hematologic disorders neoplasms. Herein, we present case an 81-year-old man EHE accompanying Waldenström's macroglobulinemia (WM). The patient complained anemia dyspnea. chest X-ray co...

Ependymomas are common spinal lesions, with the vast majority arising in an intramedullary location. Several cases have been described in the literature of ependymomas in an intradural, extramedullary location. The authors present a case of a 56-year-old female who presented with several weeks of lower back pain and weakness. MRI revealed an intradural, extramedullary enhancing mass at L1-L2. T...

We report the scintigraphic diagnosis of thoracic extramedullary hematopoiesis in a case of alcohol-related macrocytosis. A patient with liver cirrhosis and alcohol-related macrocytosis showed multiple rounded masses in the low thoracic paraspinal region on chest radiography and CT. Whole-body scintigraphy and SPECT imaging of the thorax, after nanocolloid administration, demonstrated expansion...

Astrocytomas of Conus-Cauda equina region are rare. Astrocytomas, which are intramedullary tumors, may rarely have an extramedullary component. However, primary intradural extramedullary astrocytomas are extremely rare, with very few cases reported in the literature. We describe a giant extramedullary pilocytic astrocytoma of Cauda equina in a 20-year-old male. To the best of our knowledge, thi...
