Ultrasound
The affected side (left side here) show diffuse, relatively ill-defined, echogenic breast fat tissue and increased colour flow Doppler, and enlarged lymph nodes in the axilla, with no evidence of focal skin thickening or traction, well-defined mass, or nearby extra-breast tissue invasion.
The dilated lactiferous ducts are of similar appearance bilaterally, without evidence of wall thickening or internal echogenic component or debris.
Comparison of the normally appearing, non-affected (right side here) breast and axilla demonstrate the difference in echogenicity, architecture, axillary lymph nodes, (shown), and vascularity (right side not shown).
