a hallmark spinal radiographic finding in ochronosis is:
please select your answer...
a anterior vertebral body wedging
b bamboo spine
c intervertebral disc calcification with loss of disc height
d facet joint ankylosis

Explanation:

Ochronosis is a rare genetic disorder. On spinal radiographs, a characteristic finding is intervertebral disc calcification with loss of disc height due to the accumulation of homogentisic acid - derived pigments in the connective tissues including the intervertebral discs. Anterior vertebral body wedging is not a typical finding for ochronosis. Bamboo spine is seen in ankylosing spondylitis. Facet - joint ankylosis is also not a hallmark of ochronosis.

Answer:

C. Intervertebral disc calcification with loss of disc height
