Diffuse bony sclerosis - endemic skeletal fluorosis

Case contributed by Dr Mohammad Taghi Niknejad


22 Y/O patient from Maaco - west azarbayjan - Iran (which is a city with high levels of fluoride in drinking water. )

Patient Data

Age: 22
Gender: Female

Diffuse bony sclerosis is seen with hyperdense renal parenchyma . Severe kyphosis also is noted.

Case Discussion

The findings ( in a patient with high levels of drinking water fluoride ) are consistent with fluorosis.

Endemic skeletal fluorosis is a chronic metabolic bone disease caused by ingestion of large amounts of fluoride through either water or food in geographic areas where high levels of fluoride occur naturally.
Most of the radiologic features of this disease have already been described and include :

  • increased bone density
  • blurring or haziness of trabeculae
  • compact bone thickening
  • periosteal bone formation and
  • ossification of the attachments of tendons, ligaments, and muscles
