A rare benign disorder mimicking metastasis on radiographic examination: a case report of osteopoikilosis.
Osteopoikilosis (OPK) is a rare, autosomal dominant bone disorder, characterized by multiple, discrete round or ovoid radio densities scattered throughout the axial and appendicular skeleton. OPK is usually asymptomatic but rarely there may be slight articular pain and joint effusions. OPK is generally diagnosed incidentally on radiographic examinations and may mimic different bone pathologies, including bone metastases. Radionuclide bone scan has a critical role in distinguishing OPK from osteoblastic bone metastases. In this case report, we present a young man with right hip pain due to OPK, whose plain radiogram and computerized tomography findings thought cancer metastasis.
