Four members of a family - three of whom have facial features mildly resembling those of the trichorhinophalangeal syndrome, type I, and all of whom manifested appendicular bony prominences similar to trichorhinophalangeal syndrome, type II - were found to have the radiographic findings of metachondromatosis. The radiographic manifestations and evolution of metachondromatosis are depicted in this report.
