Fibrodysplasia Ossificans Progressiva Diagnosed as Ankylosing Spondylitis: A Case Report
並列摘要
Introduction: Fibrodysplasia (myositis) ossificans progressiva is a rare and very crippling form of disease characterized by great toe malformation and heterotopic bone formation. We herein report a case of fibrodysplasia ossificans progressiva in whom the onset of complaints was after 20 years of age which led physicians to confuse this case with ankylosing spondylitis. Case Report: A 35-yearold male was referred to us by a physician for operative management of multiple joint deformities secondary to ankylosing spondylitis. However, the history and radiological findings were not consistent with ankylosing spondylitis. Clinical finding of symmetrical valgus malformations of great toes and radiological findings of heterotopic ossifications at multiple sites clinched the diagnosis of fibrodysplasia ossificans progressiva. Plans of surgery were declined after discussion with patient. Conclusion: Fibrodysplasia ossificans progressiva is an exceedingly uncommon genetic disorder. Erroneous diagnoses are very frequent and are commonly associated with apparent iatrogenic harm because of invasive diagnostic or potentially harmful therapeutic interventions. The correct diagnosis of fibrodysplasia ossificans progressiva can be made clinically even before radiographic evidence of heterotopic ossification is seen.
