I'm doing a radiology elective right now and ad the end we're supposed to do a presentation on a "radiologic topic of our choice." It seems like students typically have presented on a topic they're interested in, so since I'm interested in orthopedics I'm planning on presenting an orthopedic radiology case. I've come up with a couple ideas, but I'm looking for some more before I start putting it together. I'm looking for something more in-depth than a simple fracture, and preferentially something that is unique radiologically since that will obviosly be part of the emphasis in this elective. Anyone have any ideas to help me out? It would be much appreciated.
