Progressive vertebral fusion in a girl with spinal enchondromatosis

We report on a 9-year-old girl who presented with progressive restriction of spine mobility. Standard spinal radiographs revealed enchondromatous lesions spread out along the anterior end plates of the lumbar vertebrae and MR imaging showed progressive anterior vertebral fusion. The long bones, short tubular bones and flat bones were free of enchondromata, but arcs of chondroid calcifications were observed in the proximal femoral metaphyses. The clinical and the radiographic features encountered in our patient did not fit into any previously reported children with enchondromatosis.
