Right hip pain MR evaluation demonstrates severe osteoarthritic changes as previously observed on plain film including bone-on-bone narrowing, bulky osteophytes, large subchondral cysts and sclerotic changes. In association, mild flattening of the femoral head is observed superiorly with large either confluent subchondral cysts without complication of suspected AVN. The surrounding capsule demonstrates minimal inflammation in no significant effusion, suspected mild synovitis .Mild red marrow changes. The remaining and partially visualized pelvis is unremarkable. Surrounding musculature of the mild atrophy is otherwise also unremarkable.
Moderate avascular necrosis of the hip with superimposed severe primary or secondary osteoarthritis.
