Fluid-fluid levels in giant cell tumors of bone: Report of two cases

Abstract

Fluid-fluid levels have been described in association with aneurysmal bone cysts, telangiectatic asteosarcoma, and a chondroblastoma. We report two cases of giant cell tumors of bone with fluid-fluid levels identified by computed tomography and, in one case, by magnetic: resonance imaging. This finding has not previously been associated with giant cell tumors. The radiographic features of the fluid-fluid levels cannot be distinguished from those reported in other osseous neoplasms.
