Imaging findings. (a) Mammography showed focal asymmetrical density in the left upper area of the left mediolateral oblique position (arrow). (b) Ultrasonography confirmed the presence of a 21 mm in diameter, lobulated, low- to iso-echoic area with a high echo spot, the border of which was unclear. (c) The ipsilateral axillary lymph nodes were swollen, the largest of which was 32 mm in diameter. (d) A CT scan revealed a low enhanced mass with calcification in the middle of upper area of the left breast (left), and the ipsilateral axillary (middle) and subclavicular lymph nodes (right) were swollen. (e) MRI revealed a lobulated mass with high intensity in the middle of upper area of the left breast.; CT, computed tomography; MRI, magnetic resonance imaging.
