61-year-old female with unilateral posttraumatic osteoarthritis of the left hip. There is mild degeneration of the articular cartilage particularly along the posterosuperior aspect of the femoral head. Although evaluation of the acetabular labrum is limited due to the lack of intra-articular contrast, there is increased signal intensity throughout much of the labrum that likely represents degeneration and degenerative tearing. There is a small amount of fluid within the joint but no large effusion. There is fatty atrophy of the gluteus minimus muscle, but the remaining musculature of the left hip is unremarkable. Osteoarthritis also affects the right hip as seen on the large field-of-view images. There is also fatty atrophy of the right gluteus minimus muscle. Severe degenerative disc disease affects the level of L4/L5. Although incompletely imaged on this study, there appears to be focal disc protrusion, to the left of the midline at this level, which would be better evaluated with a dedicated lumbar spine MRI examination.
1. Osteoarthritis of the left hip.2. Severe degenerative disc disease at the level of L4/L5 with what we suspect is a protrusion of disc material at this level, however, this is incompletely imaged and could be better evaluated with a dedicated lumbar spine MRI exam if clinically warranted.
