(b) Lateral radiograph of the spine showing central beaking of the vertebrae (white arrow) and posterior vertebral scalloping (black arrow). (c) MRI spine T₂ weighted sagittal image showing thoracolumbar kyphosis and gibbus at L1–2 level (arrowheads). Note the mild spinal canal narrowing at L1 and L2 without significant compression of conus medullaris (black arrow). There is also evidence of posterior vertebral scalloping (white arrows).
