False negative for mammography resolved by tomosynthesis

Aug 21, 2006

This woman had her regular screening mammogram, which was rated as BI-RADS 1, or normal.

Some weeks later she returned because of a palpable lump in her breast. Ultrasound detected this lump and was determined through biopsy to be DCIS. Her mammogram was retrospectively reviewed and the cancer was deemed to be mammographically occult.

On review of the tomosynthesis image, taken at the same time as the mammogram, the cancer can be clearly seen near the skin line above the nipple.

This image is from a technology that is a work-in-progress and that does not have regulatory approval in certain global markets.

Study finds AI not cost-effective for breast cancer screening

Images in a 62-year-old woman who presented for screening. (A) Image from DBT screening (the synthesized 2D mediolateral oblique view of the left breast is shown) at year on was interpreted as negative and showing heterogeneously dense breast. (B) Image from molecular breast imaging screening (mediolateral oblique view) at year one reveals a 0.9-cm non-mass focal area of uptake in the left breast (arrow). (C) Targeted ultrasound scan (transverse image) shows a suspicious mass in the 3-o’clock position of the left breast, 4 cm from the nipple. Ultrasound-guided core biopsy and lumpectomy revealed a 0.9-cm grade 2 invasive ductal carcinoma, an estrogen receptor–negative, progesterone receptor–negative, human epidermal growth factor receptor 2–negative lesion, with two sentinel nodes negative (N0).

Diagnostic transverse ultrasound image of the left breast in a 64-year-old woman shows irregular hypoechoic nonparallel mass with indistinct margins corresponding to palpable finding, assessed as BI-RADS category 4. Both readers assessed mass as having associated echogenic rind with complete circumferential extent (arrowheads). Ultrasound-guided biopsy of mass yielded diagnosis of invasive ductal carcinoma (intermediate grade, luminal A molecular subtype, no lymphovascular invasion).
