    • Congenital / hereditary - osteopetrosis, pyknodysostosis
    • Endocrine - hyperthyroidism, hypoparathyroidism, renal osteodystrophy
    • Metastasis (osteoblastic) - from prostate / breast
    • Myeloproliferative disorders - myelofibrosis, mastocytosis
    • Paget’s disease (late)
    • Sickle cell disease

Subchondral Osteosclerosis

    • Look For

    • Increased bone deposition surrounding a joint, in the subchondral layer. May be associated with subchondral cysts, reduced joint space and / or osteophytes.
