C2-C7 vertebral level, large osteophyte formation, soft tissue calcification, and calcification of the interosseous membrane in the forearm [Figures 1-3]. CT scan revealed thickening and ossification of the posterior longitudinal ligament at the C1 level, thickening and ossification of the residual ligamentum flavum at C1/C2, and dural calcification at the C2 vertebral level, leading to dorsal thecal sac indentation with a residual canal space measuring 5.4 mm.
X-ray Cervical spine lateral view reveals- osteosclerosis with post op defect of laminectomy with ossification of interspinous ligament, anterior longitudinal ligament.

C2-C7 vertebral level, large osteophyte formation, soft tissue calcification, and calcification of the interosseous membrane in the forearm [Figures 1-3]. CT scan revealed thickening and ossification of the posterior longitudinal ligament at the C1 level, thickening and ossification of the residual ligamentum flavum at C1/C2, and dural calcification at the C2 vertebral level, leading to dorsal thecal sac indentation with a residual canal space measuring 5.4 mm.
X-ray Pelvis AP view- reveals Osteosclerosis with ossification of sacrotuberous ligament, sacrospinous ligament, iliolumbar and lumbosacral ligaments and bony overgrowth at ligamentous attachment site.

Skeletal survey and computed tomography (CT) [Figure 4a] scan was done revealing osteosclerosis, cervical canal narrowing due to thickening and ossification of the posterior longitudinal ligament at the C2-C7 vertebral level, and was diagnosed as a case of compressive cervical myelopathy due to skeletal fluorosis. A defect in posterior elements of the cervical spine was seen suggestive of the previous laminectomy procedure [Figure 4b].
Recent CT scan cervical spine reveals- Post op defect of laminectomy with recurrence of spinal canal narrowing due to thickening/ossification of ligamentum flavum and thickening/ossification of posterior longitudinal ligament at C2 vertebral level

T2 hyperintensity in the cervical spinal cord suggestive of severe compressive myelopathy [Figure 5]. The patient was advised operative decompression, but he refused.
