title: Radiographic and morphological features of cyst formation in idiopathic bone infarction.
abstract: Cyst formation in an infarcted bone, though rare, can be diagnosed with reasonable confidence when radiographs show an expanding lytic lesion confined by an intact but attenuated cortex. If the cortex is destroyed and a periosteal response or soft-tissue mass is present, malignant transformation should be suspected.
