title: Aneurysmal bone cyst of the calcaneus.
abstract: Aneurysmal bone cyst of the calcaneus is an uncommon entity. Radiographs showed a large lytic expanding lesion arising in the calcaneus with cortical disruption inferiorly. CT of the patient with this condition showed fluid-fluid levels that were the result of blood layering. These findings may suggest the specific diagnosis.
