Paget's disease of bone presenting with multiple cranial nerve palsies: A case report.

Paget's disease of bone (PDB) is a progressive monostotic or polyostotic osteopathy with unknown cause. It is associated with the involvement of the nervous system. The cranial nerves, spinal roots, cauda equina, spinal cord, and brain can be affected in PDB due to their close anatomical relation to bone. Hearing loss occurs in 12%-50% of patients with PDB. The optic nerve can be affected at the optic canal. The diagnosis of PDB is radiological by highlighting characteristic lesions like thickening of the cortical bone, hypertrophic and fibrillary bones. Progressive or chronic neurological deficits should be treated with bisphosphonates. We present a rare case of multiple cranial nerve palsies as the first manifestation of PDB.
