Two paraspinal masses unrelated to the aorta were discovered (figure 1). The patient had a remote history of splenectomy for hemolytic anemia and has chronic anemia. Magnetic Resonance imaging at 1.5 T was performed in an attempt to narrow the differential diagnosis amoung neural tumors, metastases, mesenchymal tumors, hematomas, developmental cysts, or extramedullary hematopoies (EMH), and less likely possibilities including paraspinal abscesses, and pseudomeningoceles.Tuesday, 26 Sep 2000 16:45:13 GMT
