MRI-Fluid- fluid levels are depicted only when the patient is lying motionless for about 10 minutes and when the scans are obtained in the plane perpendicular to that of the fluid levels. Fluid-fluid levels also are seen in many other bone lesions, such as giant cell tumors, and in telangiectatic osteosarcomas. MRI shows low to intemediate signal intensity both on t1 and t2 alon with thin low signal rim on t2 with septa and expansion. Gadolinium shows enhancement. "
