Case Report Bone and spleen uptake of technetium-99m-methylene diphosphonate in a patient with sickle-cell disease: A case report from Sudan Suliman Salih, PhD National Cancer Institute, University of Gezira, Wedmedani, Sudan Department of Diagnostic Radiologic Technology, Taibah University, Almadinah Almunawwarah, Kingdom of Saudi Arabia Received 11 July 2013; revised 24 September 2013; accepted 24 September 2013 ﺿ99 ) Tc-99m MDP ( . ٰ 99 ، . . . : ; ; 99 Abstract This case report demonstrates that measurement of the activity of technetium-99m-methylene diphosphonate in bone can play an important role in the diagnosis and fol- low-up of bone lesions in sickle-cell anaemia. In this case, the whole-body scan revealed remarkably increased activity in the spleen region, in the right ulna and in the left femoral head, consistent with bone infarcts. Bone scanning is a reli- able imaging method for early detection and diagnosis of osseous and extraosseous crises in sickle-cell anaemia.

Introduction Sickle-cell disease is one of the most common chronic haemo- globinopathies in the world. 1 It is highly prevalent in Africa and the Mediterranean region 2,3 and is strongly associated with Plasmodium falciparum malaria. 4,5 Technetium-99m-methylene diphosphonate (Tc-99m MDP) bone scintigraphy has been used to detect sickle-cell disease involving the bones. Bone uptake varies in cases of bony in- farcts, with decreasing activity due to vascular occlusion and increasing uptake during the healing phase of bone infarction. 6,7 Corresponding address: Department of Diagnostic Radiologic Technology, Faculty of Applied Medical Sciences, Taibah University, P.O.
