Ultrasound

Ultrasound showed no pathological findings. In particular, there was no circumscribed lesion corresponding to the enhancing area in the left breast seen in MRI.

Mammography

Digital mammograms demonstrated bilaterally symmetric, extremely dense parenchymal structures, ACR type 4. Under these limiting conditions, no lesions or masses were visible. No calcifications (BI-RADS right 1/left 1). PGMI: CC view P; MLO view P.

MR Mammography

MRI depicted a 5 mm mass in the central part of the left breast with increased vascularization. No other findings.

MRI Artifact Category: 3

MRI Density Type: 2

Differential Diagnosis
