Why the Angle Makes the Difference - Comparison of 15 vs. 50 degree Breast Tomosynthesis, Case 3 Video

The next case is a 51 year old woman with a past history of a fiber adenoma in the right breast and this is her mammogram from November 2016. One can see that there are scattered parenchymal densities with some mild asymmetry, and in the upper outer quadrant of the right breast there is a low density mass consistent with her known fibroadenoma. She had a time of synthesis study performed. With the wide angle the same in system and as one scrolls through in addition to the known fibroadenoma in the upper outer quadrant of the right breast, there is a small, circumscribed nodule deep to the right nipple. So the question is, is this a new nodule or has it been a longstanding finding? She had had a mammogram with. Tomosynthesis performed 18 months earlier. In May 2015, and when one scrolls through on the tomosynthesis study from. May 2015 it is actually very difficult to detect the small nodule deep to the right nipple. So the question is then, is this a new nodule is circumscribed that is probably benign, but we know that on occasion there can be cancers that do have well defined margins, so a new nodule would need some further evaluation and it is very difficult to see a nodule in this location. Zip to the right nipple. The surgeon was concerned that this was a new finding. However when we look back in the records she had had a mammogram prior. Again, 18 months earlier in November 2013 and again the mammogram in 2013 showed a circumscribed nodule deep to the right nipple. So, in summary, this woman had a mammogram in with tomosynthesis in November 2016, which demonstrated a circumscribed nodule deep to the nipple. This was difficult to appreciate on the. Thomas Enthesis study on a different system from 2015. And again is visible. In 2013, when again we were using the wide angled Seaman system, so we were. Confident this is a circumscribed nodule with the difference in appearance in 2015. Due to the differences in memory in mammographic and tomosynthesis technology. However, the surgeon was concerned that there had been a change and wasn't convinced that this was there a stable nodule. An we did biopsy the nodule and it was benign so the differences in appearances in fact due to differences in the tomosynthesis technology.
