49 year old female with biopsy proven cancer in right breast whose recent MRI showed an enhancing mass in the left breast, presents for MR-directed ultrasound with possible biopsy for left breast. Left ultrasound detected an oval mass measuring 7 x 5 x 6 mm at 1 o'clock position, 1 cm from nipple with increased blood flow. This mass corresponds to the MRI findings. PROCEDURE: The procedure and its risks, including bleeding, infection, and failure to diagnose, and expected benefits of ultrasound-guided core biopsy with percutaneous placement of a marking clip and post-procedure unilateral mammogram were discussed with the patient. Questions were answered. Consent was obtained both verbally and in writing. The time-out form was completed to confirm patient identity and side/type of procedure.The left breast was cleansed with chlorhexidine over the target area. Transducer was sterilely sheathed. Local anesthesia was obtained using 2% lidocaine superficially and at depth. A 3 mm incision was made in the skin with a #11 scalpel blade. Using aseptic technique, continuous ultrasound guidance and a lateromedial approach, three 14-gauge core needle (Achieve) specimens were obtained of the lesion. Targeting was judged very good. All specimens sank to the bottom of the prefilled container of 10% formalin. Specimen quality was judged very good.Specimens were sent to Pathology with an accompanying history sheet. Using continuous ultrasound-guidance a Bard wing clip was placed into the lesion in the usual manner. Pressure was held over the biopsy site until all bleeding subsided. The skin incision was closed with a Steri-Strip. Post-procedure digital left CC and ML views revealed the percutaneously placed clip to be in the expected location at anterior upper outer aspect, the same location where the enhancing mass was seen on the MRI. No evidence of hematoma or other complication.A pressure dressing was positioned over the biopsy site and an ice pack positioned over the pressure dressing. Post-procedure instructions were reviewed with the patient both verbally and in writing. She tolerated the procedure well with no evident complications and left the Breast Imaging Department in stable condition.The procedure was performed by Dr. Abe.
Successful ultrasound-guided core biopsy of the left breast lesion and clip placement. Pathology is pending at this time.BIRADS: 4 - Suspicious Abnormality.RECOMMENDATION: X - No Letter.
