Fluid-fluid levels within a bone lesion are best seen on MRI, although with narrow window width they can also be appreciate on CT. Their prevalence is estimated at ~ 3 % of bone and soft tissue tumours 4.
Their presence is non-specific as they be seen in both benign and malignant lesions.
The differential includes:
- aneurysmal bone cyst (ABC)
- simple bone cyst - especially after fracture
- telangiectatic osteosarcoma
