Elevated 99mTc-methylene diphosphonate (MDP) uptake in the left lung was demonstrated in a 41-year-old man with chronic lymphocytic leukemia. Lung infection was considered because the patient also had fever and pancytopenia. However, the thoracic CT performed the next day did not reveal abnormality which could explain the cause of left lung MDP activity. The repeated thoracic CTs weeks later demonstrated multiple ground-glass opacity in the left lung.
