Abstract

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 active osseous remodeling, similar to what has been observed in bone islands. Previous reports have emphasized the critical role of the radionuclide bone scan for distinguishing osteopoikilosis from osteoblastic bone metastases in patients with a known or suspected primary malignancy. In a young patient, an abnormal bone scan does not exclude the diagnosis of osteopoikilosis if the roentgenographic findings are characteristic of that entity.
