Syndromic fibrous dysplasia of the proximal femur

A woman in her 50s presented with a 1-year history of left hip pain that increased over the past 2 weeks. The pain began following a low-energy fall. During the 1-year period, she had multiple lesions in the thigh and gluteal region, which were surgically excised. She was evaluated and diagnosed with polyostotic fibrous dysplasia of the left femur with a pathological fracture and multiple intramuscular neurofibromas. She underwent closed reduction and proximal femoral nailing of the left femur. The relation of fibrous dysplasia to McCune-Albright syndrome and Mazabraud syndrome (rare) has been well documented. However, in this case, radiographically, the patient was erroneously diagnosed with Mazabraud syndrome when she had coexisting fibrous dysplasia and neurofibromatosis.
