Fig. 5. Subaerolar abscess in 49-year-old male, presenting with left breast pain and swelling.

A. Mammogram of both breasts in mediolateral oblique projections demonstrates left breast retro-areolar opacity (white arrow). Prominent left axillary node is also seen (black arrow). B. Ultrasound of left breast with color Doppler reveals hypoechoic collection in left subareolar region with echogenic internal debris and increased peripheral vascularity. Ultrasound guided tru-cut biopsy of this lesion was conducted which yielded inflammatory cells. No malignant cells were observed. C. Post contrast T1 weighted fat saturated MR imaging of both breasts in axial plane reveals subareolar rim-enhancing collection in left breast (white arrow). Fistulous tract extending to skin surface was also noted (black arrow).
