RESUMO
The purpose was to analyze the imaging features of thalassemia with extramedullary hematopoiesis in 17 patients. The 17 patients were analyzed and examined retrospectively by X-ray, ultrasonography, computed tomography, and magnetic resonance imaging. Nine cases appeared with hepatic enlargement; 12 cases presented with megalocardia or hypodensity; 15 cases had skeletal manifestations, with involvement of the ribs (66.7%), spine vertebra (40.0%), skull (46.7%), and other bones (20%). Five cases showed nonskeletal manifestations, and extramedullary hematopoiesis was found in three cases. A case presented with cholelithiasis, and hemosiderosis of the liver was found in three cases. The signs of the skeletal manifestations and nonskeletal manifestations may be useful for clinical diagnosis.
