Radiological
identification and analysis of soft tissue musculoskeletal calcifications. Disc calcifications. Sagittal CT images of the lumbar spine shows (a) calcium pyrophosphate dehydrate (CPPD) crystal deposition (arrowheads in a), (b) hydroxyapatite crystal deposition (arrowhead in b) and (c) syndesmophytes (arrowhead, in c) in three different patients. Note calcifications in ligamentum flavum and interspinous ligament associated with CPPD deposition disease (arrows in a) and ossification of disc space associated with ankylosing spondylitis (arrow in c). Note linear calcifications paralleling the vertebral endplates in b, associated with height loss, corresponding to subacute fractures in a patient with osteoporosis
Intervertebral disc calcification is a non-specific finding seen in numerous conditions.
Epidemiology
It may be observed in pediatric as well as adult populations.
Pathology
Etiology
- degenerative: relatively common and may occur in up to 6% of routine abdominal radiographs in adults
- postoperative/traumatic
- ochronosis: very dense central (nucleus pulposus) calcification associated with osteopenia; begins in the lumbar spine and ascends
- ankylosing spondylitis: associated findings should be visible
- pseudogout (CPPD): annulus fibrosus calcification
- hemochromatosis: annulus fibrosus calcification
- hypervitaminosis D: annulus fibrosus calcification (uncommon manifestation)
- transient intervertebral disc calcification is seen in children, typically in the cervical spine and spontaneously regresses
- juvenile idiopathic arthritis
- amyloidosis
- poliomyelitis
- acromegaly
- hyperparathyroidism
Morphological types
- central disc calcification
- annulus fibrosus calcification
