A lytic expansile lesion is noted in the distal of the 5th metacarpal bone that contains a thin lucent line suspected of fracture.
Case Discussion
Findings are consistent with enchondroma, a common intramedullary hyaline cartilage neoplasm with benign imaging features. As a rule, enchondromas should be asymptomatic; however, lesions of the hands or feet may present with pain from the pathological or impending fracture.
