72-year-old female. Right lateral hip pain. Evaluate for possible greater trochanter tendinitis. There is mild fatty atrophy of the right gluteus minimus muscle relative to that on the left but the gluteus medius and minimus tendons appear normal. The musculature of the hip otherwise appears normal. The bone marrow signal intensity is within normal limits. Moderate osteoarthritis affects the right hip with cartilage loss particularly noticeable along the posterior superior aspect of the hip. The edge of the anterior labrum is poorly defined and has increased signal intensity likely reflecting degenerative fraying/tearing. On the large field of view images, mild osteoarthritis affects the left hip. The pubic symphysis and sacroiliac joints are normal for patient age. Degenerative disk disease affects the visualized lower lumbar spine with narrowing of the spinal canal at L4-L5.
1. Mild fatty atrophy of the right gluteus minimus muscle but no evidence of tendon pathology or peritrochanteric bursitis. 2. Degenerative arthritic changes, as described above.
