Oxalate accumulation in the body can manifest as osteopenia or osteoporosis, and bone density scans might show high density due to calcium oxalate crystal deposition.

“and eventually that'll show up as osteopenia or osteoporosis but the funny part about that is you might also have a bone density scan that shows high density because if they're oxalate and forming calcium oxalate is starting to collect in the body it often migrates to the bones because there's so much calcium there and the bone narrow so in the bones you might have little bits of basically quartz which is harder than bone so often with an oxalate poisoning you might see a mixed scan where one part of the body has osteopenia and another part is excessively hard because it's got contaminants”
