BMD interpretation mistakes - case 18

This one was sent by another physician. The BME of the hip was 0.994 with a T-score of -0.3 two years previously. The radiologist report said:

". . . when compared to a previous exam, total bone mineral density of the total hip and femoral neck have worsened by 3 and 6% respectively."

The clinician, however, did more than just read the report; he looked at the computer printout and noticed a problem. What was it?
