Beyond the greater trochanter: a pictorial review of the pelvic bursae

Purpose Review the MRI appearance of different bursae located throughout the pelvis, including the pertinent osseous and musculotendinous anatomy. Materials and methods Bursae are potential spaces that reduce friction between opposed moving components which can become inflamed, clinically mimicking internal derangement. Results This series illustrates the most common as well as lesser-known pelvic bursae. Common causes of bursitis including overuse, trauma, and infection are presented. Conclusion Multiple bursae are located throughout the pelvis. It is important for radiologists to recognize bursitis as a potential etiology of pain and be familiar with their anatomical locations in order to guide appropriate management.
