Reason: eval lucency seen on plain film History: new left hip pain The proximal femoral lucency seen on recent radiographs likely corresponds to a focus of cortical thinning along the posterior aspect of the femur at and below the level of the lesser trochanter. This appears benign and we see no focal lesion within the medullary bone. There is patchy intermediate bone marrow signal intensity on T1-weighted images likely representing residual red marrow. Mild osteoarthritis affects the hip with cartilage degeneration. There is mild subchondral edema within the femoral head and acetabulum. Although this examination was not protocoled for detailed evaluation of the acetabular labrum, there is intermediate signal intensity within the superior labrum likely representing degeneration/degenerative tearing. There is a small lobulated collection of fluid signal intensity along the anterior superior aspect of the hip joint which may represent a paralabral cyst. Additional fluid signal intensity along the posterior aspect of the femoral neck may represent a small amount of fluid within the joint perhaps associated with a mild synovitis. On the large field-of-view images, mild osteoarthritis affects the right hip and degenerative disc disease affects the lower lumbar spine.
1. Osteoarthritis of the left hip and other findings as described above.2. The lucency within the proximal femur likely corresponds to an area of benign cortical thinning. We see no underlying medullary lesion.
