A Bizarre Bone Scan of Fibrodysplasia Ossificans Progressiva

A 27-year-old woman had progressive bony ankylosis over both hands since she was 5 years old. Bony ankylosing over the peripheral joints and spine slowly progressed, and scoliosis surgery was performed at age 14. Recently, she developed difficulty walking, changing position, and opening her mouth. A neurologist was consulted and ruled out the suspicion of narcolepsy. Chest CT showed ankylosing spondylitis. A bone scan showed a bizarre pattern with radiouptake to the left maxilla, bilateral sacroiliac joints, left middle third femur, and soft tissue uptake over bilateral arms, legs, and pelvis. Regional radiograph suggested fibrodysplasia ossificans progressiva.
