Vascular chest wall lesion mimicking a breast tumor on screening mammograms: Report of a case

Multimodality imaging review of breast vascular lesions

Breast vasculature is visualised on all screening and diagnostic imaging of the breast. Various vascular breast lesions exist, spanning from chronic systemic processes, congenital malformations, post-traumatic sequela, benign masses, to malignant tumours. Accurate diagnosis of vascular lesions on breast imaging can be difficult due to overlapping characteristics. Radiologists should be aware of key multi-technique imaging features to make an accurate diagnosis and to avoid unnecessary biopsies. This article reviews the normal vascular anatomy of the breast, commonly used imaging techniques to diagnose vascular lesions, and an in-depth review of various vascular breast lesions. Finally, management recommendations and clinical guidance are discussed so that the radiologist can appropriately triage these patients.
