TC-99M MDP UPTAKE IN OSTEOPOIKILOSIS

A Tc-99m bone scan of a patient with classic roentgenographic findings of osteopoikilosis revealed multiple foci of increased activity that corresponded to many of the sclerotic foci on the roentgenograms. The authors presume that the abnormal bone scan in this patient reflects a ctive osseous remodeling, similar to what has been observed in bone is lands. Previous reports have emphasized the critical role of the radio nuclide bone scan for distinguishing osteopoikilosis from osteoblastic bone metastases in patients with a known or suspected primary maligna ncy. In a young patient, an abnormal bone scan does not exclude the di agnosis of osteopoikilosis if the roentgenographic findings are charac teristic of that entity.
