Skeletal fluorosis
Updates to Study Attributes
Cervical spine
Significant thickening and ossification of posterior longitudinal
ligament is seen from C2 to C3 levels, causing severe compression of cord.
Intramedullary hyperintensity is seen from C1-2 to C3-4 levels.
Dorsal spine
Significant thickening / ossification of ligamentum flavum is seen at D10-11 level, causing mild to moderate compression of cord.
Intramedullary hyperintensity is seen from D9-10 to D10-11 levels.
Multilevel thickening / ossification of posterior longitudinal ligament and ligamentum flavum seen, causing mild to moderate compression of ventral, dorsal thecal sac, indentation of surface of cord and compression of neural foramina at places.
Reduced signal intensity is seen involving all visualized bones on all sequences.
Lumbar spine and sacroiliac joints
Apart from degenerative spondylotic changes, there is reduced signal intensity of all visualisedvisualized bones on all sequences.
Updates to Study Attributes
CT of cervical spine of the same patient as above shows ossification of posterior longitudinal ligament causing centrl canal narrowing, increased density of all visualisedvisualized bones suggesting osteosclerosis and multiple other calcific enthesitis.
