title: Unusual bone marrow hyperplasia in a case of thalassemia intermedia.
abstract: A case of beta thalassemia intermedia is described. Beside the typical hematologic picture and extramedullary erythropoiesis in the liver always present in such a clinical form, atypical masses due to foci of erythropoiesis were found at paravertebral, parasternal and subcostal sites. The size of these masses caused problems in differential diagnosis; they have been solved by computerized axial tomography.
