Vascular lesions of the breast comprise a heterogeneous group that includes a variety of benign, atypical, and malignant lesions. These are a diagnostic challenge given variable clinical, radiological and pathological presentation, especially when they are small and asymptomatic. We present 2 cases of these rare lesions of the breast which were occult to mammographics and ultrasound studies. Both the lesions were detected only on magnetic resonance imaging, most helpful in the diagnosis of these rare tumor. Histopathological examinations following the magnetic resonance guided biopsies, were initially interpreted as negative for breast cancer in both cases. These turned out to be respectively a low grade angiosarcoma and a benign vascular lesion after a new histopathological examination following a larger magnetic resonance guided biopsies performed in light of the radiology-pathology discordance. Although rare, it is important to consider vascular tumours of the breast; radiologists need to be aware such tumors may present non-specific imaging features.
