Abstract
Purpose. We studied six patients with sickle cell disease (SSD), five homozygous for sickle cell anemia and one with sickle betathalassemia, in whom rounded intrasplenic masses proved to be preserved functioning splenic tissue.Materials and methods. Available images including computed tomography, ultrasonography, bone scans (Tc-99m MDP), liver spleen scans (Tc-99m sulfur colloid), and MRI were evaluated.Results. The masses were low density on CT (in an otherwise calcified spleen), hypoechoic relative to the echogenic spleen on US, and had the imaging characteristics of normal spleen on MRI. They failed to accumulate Tc-99m MDP but did demonstrate uptake of Tc-99m sulfur colloid.Conclusion. In a patient with SSD and intrasplenic masses, proper correlation of multiple imaging modalities will establish the diagnosis of functioning splenic tissue and avoid mistaken diagnosis of splenic abscess or infarction.
