Fibrous dysplasia is a condition leading to abnormal differentiation of osteoblasts which leads to replacement of normal bone with fibrous stroma [1-3]. It may involve single bone (monostotic) or multiple bones (polyostotic). It may affect any bone however; skull and ribs are the commonest [2,4-6]. It is usually asymptomatic and is an incidental finding. It may become symptomatic when complicat...

Whole-body bone scans and whole body (18)F-fluorodeoxyglucose positron emission tomographic/computed tomographic scans are sensitive for detecting bone metastasis in patients with breast cancer. However, it is often difficult to discriminate between bone metastasis and other nonmalignant bone lesions. Polyostotic fibrous dysplasia is a rare disorder characterized by the osteoid medullary cavity...

Fibrous dysplasia of bone is a skeletal disease due to a specific mutation in the GNAS1 gene with a broad spectrum of clinical presentations ranging from isolated monostotic and polyostotic forms to associations with other extra-skeletal manifestations (McCune-Albright syndrome). The main complications are bone pain, deformities and fractures and sometimes cranial nerve compression and the deve...

INTRODUCTION Fibrous dysplasia is a rare benign disorder of the skeletal system characterized by fibro osseous proliferation with intervening areas of normal or immature bone in the intramedullary region. It can either be a monostotic (involves one bone) or a polyostotic (involves more than one bone) presentation and usually occurs equally in males and females. Deformities like scoliosis and sh...
