Multiple extraosseous accumulation of 99mTc-MDP in acute lymphocytic leukemia and reference to literature

Technetium-extraosseous accumulation of technetium-99m-methyl diphosphonate ((99m)Tc-MDP) on bone scan is not usual. It was described and in various diseases with solitary spleen or lung uptake. Simultaneous splenic, pulmonary and renal concentration of (99m)Tc-MDP has not been illustrated previously. Herein, we present a 17 years old man with acute lymphocytic leukemia (ALL) in whom (99m)Tc-MDP was accumulated in the spleen, both lungs and the kidneys. Related literature was mentioned.
