Unusual ultrasound report
First Mammogram (age 40) required a call back because of finding in left axilla. Ultrasound performed a week later and this was the outcome. I understand the BIRADS rating, but this is very confusing. What is a large fluid filled area? I can feel fluctuating lump (soft, no skin changes) on the my left side extending to the back.
LEFT AXILLA ULTRASOUND:
No abnormal lymph nodes were identified. There is an irregularly-shaped fluid collection that is in
the left axilla but also extends posteriorly to the posterior axillary line. The shape makes it
difficult to give complete measurement, but this has AP extension of at least 6-7 cm. These sites
in the more axillary portion is about 4.4 x 1.5 x 3.6 cm. The cause of this finding is uncertain
although it currently appears benign. I believe this fluid collection accounts for the mammographic
appearance. I am not aware of any history that would explain this finding.
BI-RADS Category 3 - Probably benign
