|Findings: Homogenous focal areas of increased radiopacity, with round to ovoid shape in the femoral head and supra-acetabular ilium.|
|Diagnosis: bone islands|
|Discussion: Typically round to ovoid in shape and less than 1cm in size, bone islands are common in the femoral head/neck area and in the flat bones of the pelvis. They are occasionally worrisome when larger than usual and/or when seen on radiographs of older patients, where blastic metastatic disease is a differential consideration. In younger patients, a solitary bone island can also mimic the reactive sclerosis associated with osteoid osteoma, particularly in the femoral neck.|
