A 45-year-old female had a one week history of left breast fullness and hardness. She suffered pain when lifting her left arm over her head. She had no history of trauma, malignancy, systemic illness or regularly taken medications. She was referred to radiology for an ultrasound (Figure 1). This was followed by a breast MRI (Figures 2-3). Due to the findings on the two examinations, a short term follow up MRI was performed (Figures 4-5).
