Stage 3 Intraosseous Lipoma on the right side of pelvic bone. What kind of surgery will the require?

Thank you for sharing your question. I would consult with an orthopedic surgeon at UPMC to discuss the best surgical option.  A small window could be made into the bone in order to remove the lipoma if they feel this is the cause of your hip pain. Hope this helps.

Hello Nette0109, Sorry to hear about your diagnosis. The good news is that the tumor is benign, and extremely rare, a center of excellence near you with orthopedic surgeons who have experience in pelvic bone surgery can better guide you. they may elect to watch it, sometimes the tumor can cause breaks in the bone which need to be treated, and often bone from elsewhere to fill that area of removed broken bone (A bone graft) but this is uncommon, and the orthopedists may ask for an MRI or more imaging to tell if there is anything to do. Most do not recur after excision. 
Hope this answer encourages you to seek specialist opinion
