Ollier disease with digital enchondromatosis: anatomic and functional imaging.

Ollier disease is a rare skeletal disorder characterized by multiple enchondromas at metaphyseal regions of the bones. The disease is nonhereditary and usually the result of postzygote mutations during development. We present the features of digital enchondromatosis on bone scintigraphy, PET/CT, radiographs, and MRI in a patient, with a childhood diagnosis of Ollier disease.
