Arteriovenous Malformation of the Breast; Report a Case

Abstract

Background: Arteriovenous malformation (AVM) of the breast is a rare condition that is usually incidentally detected as discoloration of the skin. Patients are asymptomatic, and it is mostly left undisturbed. However, the closest differential diagnosis of primary angiosarcoma of the breast can have a similar imaging appearance. Multimodality imaging will help to differentiate between the two, and in very few cases, tissue diagnosis warrants confirmation. Case presentation: We hereby report the case of a young female who initially presented with swelling and discoloration near her face and neck and who, on a one-year follow-up, incidentally noticed discoloration over her left breast. She underwent an ultrasound, a dynamic contrast-enhanced MRI of both breasts and a dedicated left breast X-ray mammogram. Conclusion: With all these modalities confirmed, the discoloration was caused by an AVM of the breast.
