Presentation A 32-year-old lactating woman presents with severe localized pain in her left breast and fever for 2 days. An ultrasound of the breast was performed.
 
 
 
Caption: Scan of the painful area of the left breast
Description: The area of concern shows decreased echogenicity when compared to the rest of the breast parenchyma. This area is ill-defined and shows loss of normal architecture.
 
 
 
Caption: Comparative views of painful [right] and painless [left] areas
Description: This view clearly delineates the ill-defined hypoechoic area. The loss of planes with the normal breast tissue on the affected side is clearly appreciated in this comparative view.
 
 
 
Caption: Comparative color Doppler views
Description: The hypoechoic region demonstrates increased vascularity. This is consistent with an inflammatory process.
 
Differential Diagnosis Focal mastitis, lobular carcinoma, ductal carcinoma, lactational adenoma
 
Final Diagnosis Focal mastitis
 
Follow Up Follow up ultrasound after a course of antibiotics showed resolution of these findings.
