title: Rugger-jersey vertebrae.
abstract: We present the case of a 71-year-old patient with rugger-jersey vertebrae who was referred to us with a tentative diagnosis of Paget's disease. After considering other conditions causing similar bone sclerosis, such as metastases, lymphoma, renal osteodystrophy, myelofibrosis, thalassemia, and Gaucher's disease, we agreed on a diagnosis of osteopetrosis. This is a rare entity of genetic origin, manifest by variable generalized symmetric skeletal sclerosis caused by defective bone resorption.
