44 year old female who was recalled from screening mammogram for new asymmetry in the right axillary tail. Mammogram: An ML, MLO view and two spot compression views of the right breast were performed digitally and reviewed with the aid of R2 CAD 9.3. The breast parenchyma is composed of scattered fibroglandular density, unchanged in pattern and distribution. 7 mm asymmetry best seen on the MLO and ML view appears circumscribed, oval and does not have a definite correlate on the CC spot compression view. Ultrasound: Targeted right lower axillary/upper, outer quadrant ultrasound was performed. A 7 x 4 mm benign intramammary lymph node is identified with normal morphology.
Asymmetry in the right lower axillary region, most likely corresponds to a benign intramammary lymph node. No mammographic evidence of malignancy. As long as the patient's physical examination remains normal, right unilateral diagnostic mammogram is recommended in 6 months to confirm stability. Results and recommendation were discussed with the patient.BIRADS: 3 - Probably benign finding.RECOMMENDATION: 3B - Followup at Short Interval (1-11 Months).
