Abstract:
OBJECTIVE. The objective of this article is to define the clinical significance of asymmetric ductal ectasia by a review of literature and to describe the imaging findings. CONCLUSION. Asymmetric ductal ectasia has a significant risk for malignancy and high-risk lesions. The findings on conventional imaging may be subtle and easily overlooked. Asymmetric ductal ectasia should be included in the search pattern during image interpretation. Tissue sampling is usually warranted. Ultrasound is critical in identifying ductal abnormalities to guide biopsy.
