An osteoclastoma may present with localised bone pain or a pathological fracture. On examination, there may be palpable local 'egg-shell crackling' due to thin layers of expanded bone around the osteoclastoma.

Radiologically there may be a 'soap bubble' appearance due to persistence of bone trabeculae within the osteoclastoma area. Often the tumour abuts against the joint margins. The cortex of the tumour is often very thin and may be ballooned or even perforated.
