Pain with weightbearing and hip flexion. Evaluate for labral tear or hip flexor injury. ACETABULAR LABRUM: Best seen on sagittal image 21 of series 701 and oblique sagittal image 14 of series 801 is a thin band of intermediate signal intensity traversing the anterior superior labrum at approximately the 2:00 position, indicating a tear. The posterior labrum appears intact.ARTICULAR CARTILAGE AND BONE: I see no fluid-filled articular cartilage defects. There is slight subjective prominence of the anterosuperior aspect of the femoral head-neck junction, with a borderline alpha angle of 55 degrees. There is a small, mild focus of edema along the medial aspect of the femoral neck that could represent a small focal stress reaction, but I see no fracture line or signal abnormality in the adjacent cortex. There appears to be transitional lumbosacral morphology, with a slightly hyperkyphotic lumbosacral junction. Small foci of fluid signal intensity arising from the facet joints of the lower lumbar spine suggest synovial cysts and osteoarthritis. These findings are not adequately optimally assessed on this hip MRI study, and would be better evaluated with lumbar spine radiographs and perhaps lumbar spine MRI. There is a small focus of edema-type signal within the inferior aspect of the right sacral wing adjacent to the sacroiliac joint which I suspect is degenerative in etiology. The remaining visualized bone marrow is unremarkable.SOFT TISSUES: There is edema-type signal within the anterior soft tissues of the hip left hip that I suspect is iatrogenic related to the injection portion of the procedure. The ligamentum teres appears intact. I see no muscle or tendon tear/disruption. Thin bandlike low signal intensity traversing the lateral subcutaneous fat of the left hip likely reflects prior surgery.
1.Tear of the left anterior superior labrum at the 2:00 position.2.Small focus of mild edema within the medial aspect of the base of the left femoral neck which could conceivably represent a mild stress reaction, but I see no discrete fracture line or signal abnormality in the cortex.3.Transitional lumbosacral morphology with facet joint osteoarthritis and possible synovial cysts. These findings would be better assessed with lumbosacral spine radiography and/or lumbar spine MRI, if clinically warranted.4.Other findings as above.
