Paget’s disease.

He has cataracts and prostatic outflow obstruction, common pathologies in older people. However, his deafness and back pain are due to Paget’s disease. The Xray shows a coarseness of the L2-4 vertebral bodies and blurring of the cortico-medullary junction. The bodies are also quite flat and there is thickening of the right border of L3.
