A "hair-on-end" pattern may be noted on skull radiographic images of a patient with sickle cell anemia. This occurs because the trabeculae radiate outward. Oral manifestations are seen on dental radiographs. A loss of trabeculations takes place, with the appearance of large, irregular marrow spaces. Polycythemia is characterized by an increase in the number of circulating red blood cells. Aplastic anemia is characterized by a generalized decrease in circulating blood cells. Thalassemia is the name of a group of inherited disorders of hemoglobin synthesis.
