Femoral bone cyst
Hello, I am a 38 year old male, and 4 years ago on pelvic MRI scan was diagnosed with the bone cyst in the lateral neck of my right femur, 5mm in diameter. I haven't checked this in the meantime, and had an whole-body MRI seven days ago. It turns out that the femoral cyst is now 1cm in diameter, ie. has doubled its size. Radiologist says it is just a cyst, but why is it growing? How can one determine whether it is malignant or benign? Anyone with a similar problem? Any inside would be greatly appreciated.
Regards to all, Danny
