It is quite obvious that the osteochondromas grew during the 8-year interval, just like the patient himself also grew and developed. Some of the interesting features worth commenting are:
- Firstly, the knees - the previously presented exostosis increased in dimensions and new bone lesions raised from the fibulars' heads and proximal diaphysis.
- Secondly, the hip and femurs - notice the metaphyseal bulging with a coxa valga deformity of both proximal femurs, besides the prominent undertubulation. Although it is not so evident, there is also the Erlenmeyer flask deformity.
- Thirdly, the ribs - although it is not easily seen, there is a pedunculated osteochondroma developing from the inferior surfaces of the eighth and ninth left ribs.
