18-year-old female presents with chronic left hip pain, evaluate for labral tear. ACETABULAR LABRUM: There is curvilinear intermediate signal intensity within the anterior superior labrum that may represent surgical suture material, however, there is no gadolinium-filled defect to suggest a labral tear. Small foci of signal void in the anterior portion of the joint are favored to represent air bubbles.ARTICULAR CARTILAGE AND BONE: No gadolinium-filled articular cartilage defects are identified. Bone marrow signal intensity is normal. Scalloping of the femoral head/neck junction suggesting prior osteoplasty.SOFT TISSUES: Defect in the anterior capsule reflects prior surgery. The ischiofemoral space measures approximately 8 mm, which is narrowed. There is perhaps minimal edema in the quadratus femoris muscle. These findings suggest the possibility of iliofemoral impingement, although the clinical significance of this is uncertain. The ischiofemoral space on the left also appears narrowed. Otherwise, the musculature of the hip appears normal.ADDITIONAL
1. Surgical changes of a prior hip arthroscopy/surgery as described above. No labral tear is identified.2. Narrowing of the ischiofemoral space with minimal edema and the quadratus femoris may reflect ischiofemoral impingement, although the clinical significance of this is uncertain.
