case_images: B ultrasonography uncovered a mass measuring 12.6 cm in diameter in the lateral quadrant of the right breast with enlarged axillary lymph nodes and was staged as BI-RADS 5 (Figure 2).
case_images: Results of chest computed tomography (CT). (A) The red arrow shows a large breast tumor with thickened skin. (B) The red arrow shows a nodule in the upper lobe of the right lung, indicating lung metastasis. (C) The red arrow shows another nodule in the upper lobe of the right lung, suggesting lung metastasis. (D) The red arrow shows abnormal bone density on the thoracic third vertebral body (T3), indicating bone metastasis.
