Imaging and Excision findings of upgraded cases showing focal atypical ductal hyperplasia on core needle biopsy
| Imaging Findings | Excision Findings | |||||||
|---|---|---|---|---|---|---|---|---|
| Case | Imaging modality | Lesion type | Lesion diameter (mm) | Target removed by CNB | DCIS at excision | DCIS grade | IC at excision | IC grade |
| 1 | MMG | Ca++ | 7 | No | Yes (3 mm) | Intermediatea | No | - |
| 2 | US | Mass | 8 | No | Yesb | Low | No | - |
| 3 | MMG | Ca++ | 5 | No | Yes (2.1 mm) | Lowa | No | - |
| 4 | MMG | Ca++ | 8 | No | Yes (30 mm) | Intermediatea | No | - |
| 5 | MMG | Ca++ | 4 | Yes | Yes (12 mm) | Intermediatea | No | - |
| 6 | MMG | Ca++ | 7 | Yes | No | - | Yesc (4.5 mm) | Grade 1 (tubular carcinoma) |
| 7 | MMG | Ca++ | 6 | No | No | - | Yesc (6 mm) | Grade 1 (tubular carcinoma) |
a
Calcifications identified in DCIS
b
DCIS difficult to quantify due to dispersed nature, focally involves intraductal papilloma
c
Not associated with the biopsy site
MMG – mammogram, US – ultrasound, Ca++ - calcifications, CNB – core needle biopsy, DCIS – ductal carcinoma in situ, IC – invasive carcinoma
