case_images: Vertebral and spinous processes deformities and compressions (white arrows).. Spinal cord compression and spinal canal stenosis on cervical, thoracic, and lumber spine (yellow arrows). Epidural mass effect on T4, T9 (red arrows).. MRI (cervical, thoracic, and lumbar) without contrast; T2 sequence shows the following:

case_images: MRI of the cervical spine (Fig 1) with the same vertebral characters showed vertebral compression of the spine on C6-C7.
case_images: Diffused lytic lesions along all vertebrae with vertebral erosions and destruction of vertebral bodies and spinous processes (black arrows).. Cortical kidney calcifications (white arrows). Hepatosplenomegaly.. CT scan; bone (A+B) and abdominal (C) windows shows the following:

case_images: Vertebral and bone marrow biopsies (H&E stain, x200). A significant number of bright needle-shaped oxalate crystals are noted within osseous tissue.

case_images: Finally, pathologic study results from vertebral and bone marrow biopsies showed necrotic osseous materials involved by depositions of CaOx crystals, which form a radial pattern that encircled and engulfed by epithelioid and giant cells foreign body reaction (Fig 3).
case_images: Vertebral and bone marrow biopsies (polarized light). Oxalate crystals showed positive birefringence.
