Ultrasound findings of a 39-year-old male patient with 2 lesions (A), (B) on the upper back prior to surgical excision. This is the most recent ultrasound obtained prior to surgery—2 months prior to resection. At the time of surgical resection, intraoperative ultrasound was utilized to localize the lesions; although images from the surgery were not saved in the electronic medical record, the operative dictation describes 2 discrete subcutaneous hypoechoic masses measuring approximately 4 mm and 1 cm in greatest diameter, respectively, as seen in the images. These lesions were also FDG avid on PET. Final pathology showed 2 benign lymph nodes with follicular and paracortical hyperplasia. FDG, fluorodeoxyglucose; PET, positron emission tomography.
