Yes, Its possible to have Cushings syndrome even after consuming steroids for just 2 years. Looking at her wrist joint synovial thickening it seems her RA would have been for a long duration. I searched Pubmed and found there are case reports showing that it may develop even with a single dose!! One however needs to find a better study of patients of steroid induced Cushings with respect to duration of consumption of steroids. A future project for one of you?? The reason other RA patients or others consuming steroids don't develop it is because steroid dosage is  judiciously regulated while treating such patients. Such patients are also put on DMARDs (disease modifying antirheumatoid drugs) that bring down the steroid requirement even further.
