Avascular necrosis ACETABULAR LABRUM: Evaluation of the acetabular labrum is limited given the lack of intra-articular contrast. Within these limits, there is no evidence of gross labral detachment although there is some slight signal irregularity within the anterior labrum for example on series 6 image 24 and series 9 images 8 through 11.ARTICULAR CARTILAGE AND BONE: There is serpentine low T1 signal intensity involving the left femoral head indicating avascular necrosis. Similar findings are also evident in the right femoral head and a tunnel from prior decompression is identified extending through the right femoral head neck junction. The articular surface of the left femoral head is maintained. Alignment is normal. There is a trace amount of fluid within the joint but no joint effusion.SOFT TISSUES: No significant abnormality noted. ADDITIONAL
1. Avascular necrosis of the left hip without evidence of articular collapse.2. Slight signal irregularity of the anterior labrum.
