osteochondroma ( RID4136 )
The exostosis has not changed in 3 years. XRs show that it points toward the hip joint, which is odd for an osteochondroma. MRI confirms medullary and cortical continuity and suggests a hyaline cartilage cap, so I believe its a true osteochondroma. Ive not seen one arising from an apophysis (in this case, the lesser trochanter); would we consider this a corollary of Trevors disease? or is that just for intra-articular rather than epiphyseal osteochondroma? This will be resected as it is causing painful friction. Note in slide 4 that it is separate from the iliopsoas insertion and does not represent an old post-traumatic exostosis from previous lesser trochanteric avulsion
