Background
Hip pain is a common and disabling condition with a broad differential, presenting a diagnostic challenge. Patients often localize hip pain to one of four anatomic regions: anterior, lateral, posterior hip or buttock, and medial hip or groin. This education exhibit will primarily focus on extra-articular sources of hip pain, utilizing an anatomy-based approach.

Educational Goals / Teaching Points
The objectives of this educational exhibit are to review pertinent osseous and soft tissue anatomy of the hip; discuss differentials for extra-articular hip pain utilizing an anatomy-based approach (anterior, posterior, lateral, and medial); and demonstrate imaging features of common and rare causes of extra-articular hip pain.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
This exhibit includes: 1) anterior iliopsoas bursitis and internal snapping, meralgia paresthetica, stress fracture, and rectus femoris injury; 2) lateral external snapping, greater trochanteric bursitis and pain syndrome, gluteus medius and minimus; 3) posterior sciatic nerve/piriformis syndrome, ischiofemoral impingement, hamstring tendons/ischiogluteal bursitis, ischial apophysitis; and 4) medial/groin osteitis pubis and proximal adductor tendons.

Conclusion
Hip pain is a common and disabling condition that can be localized to one of four anatomic regions: anterior, lateral, posterior hip or buttock, and medial hip or groin. The radiologist must gain a precise understanding of anatomy, imaging features and differential diagnosis for accurate imaging interpretation and reporting.
