Radiograph of multiple enchondromas of the hand in Ollier disease
AP radiograph of the hand shows lesions in the third metacapal head distally and in the proximal and middle phalanges proximally that are metaphyseal in location, expansile and lytic in appearance, with a narrow zone of transition and without periosteal reaction.

The diagnosis was enchondromatosis without any associated soft tissue lesions and therefore diagnosed as Ollier disease.
