Neonatal mastitis and abscesses are an uncommon finding. The peak incidence is at three weeks of age. Under two weeks of age the incidence is equal amongst male and females 1. After that time there is a predilection for females.
The sonographic features of neonatal mastitis were demonstrated in this case including:
- poorly marginated breast bud 2
- thickened, hyperechoic and hypervascular subcutaneous fat 1
- mass with mixed echogenicity and internal vascularity 1
The anechoic focus seen superficially within the breast tissue had no internal vascularity with peripheral hypervascularity which is suggestive of an abscess 2.
The child was treated with IV antibiotics and incision and drainage. Microbiology identified Staphylococcus aureus.
