Ms. Davis is a 27-year-old female with history of myeloid sarcoma in the right breast, status post radiation, presenting for follow-up of palpable lesion in the right axilla. A targeted right ultrasound was performed for the palpable area of concern, in preparation for ultrasound guided biopsy. In the right axilla, there is revisualization of a superficial, focally echogenic area, which currently measures 6 x 7 mm, compared to 8 x 9 mm (from prior ultrasound 09/20/2016). This area is much less prominent when compared to prior ultrasound and has a sonographic appearance typical for benign fat necrosis.
Palpable area of concern in the right axilla corresponds to a hyperechoic area which has decreased in size when compared to the prior study. Sonographic findings are typical for benign fat necrosis. After discussion with Dr. Artz and patient, a plan was made to have a short term 2-4 week follow-up ultrasound and physical exam (performed by Dr. Jaskowiak) to reassess the area. If the area persists or is larger, than an ultrasound-guided biopsy can be performed at that time. All results and recommendations were discussed with the patient, Dr. Artz and Dr. Jaskowiak. BIRADS: 3 - Probably benign finding.RECOMMENDATION: 3B - Followup at Short Interval (1-11 Months).
