Clinical image: Fibrodysplasia ossificans progressiva seen on three-dimensional computed tomography



Illustration 1.

The patient, a 28-year-old woman, was admitted to our hospital with trismus, abnormal soft tissue tumors, and diffuse ankylosis of the limbs and trunk. These symptoms had progressed following 2 surgeries, 19 years and 23 years previously. Whole-body 3-dimensional computed tomography scanning revealed diffuse calcification over the soft tissue of the neck, both arms, chest wall, and left thigh. The patient was diagnosed as having fibrodysplasia ossificans progressiva, a rare inherited disease characterized by progressive soft tissue ossification occurring after minor injuries. Three-dimensional computed tomography can be a useful tool for diagnosis of this condition.
