Multiple regions of absent bone mineral and marrow function in a patient with chronic renal failure

99mTc-methylene diphosphonate bone mineral and 99mTc-sulfur colloid bone marrow studies were performed on a patient with chronic renal failure. Multiple regions of absent deposition of both radiotracers were noted, involving the right ilium, multiple ribs, and the manubrium. Radiographs of these bones were normal. The findings suggest absent regional perfusion of the involved bones.
