Cytomegalovirus (CMV) rarely causes disease in immunocompetent individuals but may cause severe disease in immunocompromised patients. We report the case of a young woman who had undergone multiple transfusions and splenectomy for homozygous β-thalassemia. She presented with prolonged fever and respiratory distress. Although broad-spectrum antibiotic therapy had initially been administered, the patient had clinically deteriorated. Serology and molecular blood testing established CMV infection and viremia. Computed tomography of the chest demonstrated pneumonitis and she was successfully treated with a 3-week administration of ganciclovir. In β-thalassemia patients who undergo splenectomy necessitating multiple blood transfusions, CMV infection should be considered as a differential diagnosis.
