Figure 1 Magnetic resonance imaging. A: Preoperative MRI indicated collapse of the L2 vertebral body and the formation of an intravertebral cavity-like structure indicated by the arrows; B: T2WI with fat suppression (T2WI FS) showed a fluid-filled intravertebral vacuum, with little of the upper endplate structure remaining indicated by the arrows; C and D: T2WI showed a low signal at the cavity edge, indicating vertebral bone necrosis and fibrous perichondrium formation, indicated by the arrows.
