Scintigraphic findings of multiple osteochondromas

Multiple osteochondromas (hereditary multiple exostoses, diaphyseal aclasis, cartilagenous exostoses) are anomalies of bone development in which multiple cartilagenous exostoses grow out from the cortical surface, mainly involving ends of the long bones. While radiographic characteristics of multiple osteochondromas have been well documented, there is little information concerning the place of bone imaging in this disease. A patient with multiple osteochondromas whose skeletal scintigrams correlate with the concurrent radiographs is presented. Although there is no specific pattern scintigraphically, the abnormal, irregular increase in radioactivity at the end of the long bones may raise a possibility of this disease entity.
