POEMS syndrome in a 15-year-old boy: radiological findings.

POEMS syndrome is a multisystem disorder related to a plasma-cell dyscrasia. It is usually seen between the ages of 40 and 50 years and is very rare in childhood. Radiologically, this syndrome is characterized by sclerotic focal bone lesions with a normal radionuclide bone scan. We report a case of POEMS syndrome in a 15-year-old boy in whom plain radiographs and multidetector-row spiral CT (MDCT) provided information that was helpful in the clinical assessment.
