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.
