Figure 2 Computed tomography imagines. A: Axial computed tomography imaging demonstrating osteochondroma protruding from right spinous process/Lamina junction; B: Sagittal computed tomography imaging at the level of the L5/S1 facet joint depicts mass involvement of the right inferior articular process of L5. An ultrasonic bone scalpel was used to remove the mass en bloc from the articular process without disrupting the facet capsule.
