One of the most common radiological findings in skeletal fluorosis is osteosclerosis – a hardening of bones with a blurring of the trabecular structure. In advanced cases, the osteosclerotic form of fluorosis may closely resemble the appearance of osteopetrosis, a “marble bone” disease in which the bones are dense, but fragile and prone to fracture.
Fluoride & Osteopetrosis:
“In the differential diagnosis (of skeletal fluorosis) one must think of osteopetrosis (marble bones), metastatic cancer, and Paget’s disease.”

“Other diseases simulating radiographic features of fluorosis are Paget’s disease, parathyroid hormone disorders, osteopetrosis, chronic renal failure, myelofibrosis, hypophosphatemic osteomalacia, and diffuse blastic metastases.”

“In addition to osteopetrosis and osteoblastic metastases, the differential diagnosis (of skeletal fluorosis) includes Paget’s disease…”
