Contralateral axillary lymph node metastasis is a rare entity in breast cancer and is currently classified as a distant metastasis; however, recent studies have proposed aggressive curative treatment since this entity may manifest as a locoregional disease. Herein, we report a rare case of contralateral axillary lymph node metastasis that presented with imaging findings 22 months after the initial breast cancer diagnosis in a 67-year-old female. The patient underwent lymph node dissection of the axilla with adjuvant chemotherapy and radiotherapy. A follow-up examination 6 months after surgery showed no evidence of tumor recurrence or metastasis.

Angiosarcoma of the breast is a rare malignant sarcoma of endovascular origin that presents with various radiological findings. We encountered a case of angiosarcoma of the breast presenting as an irregular indistinct hyperechoic mass on ultrasonography, with a large single angiosarcoma of the spleen in a previously healthy 36-year-old female. Herein, we report the imaging and pathologic findings and review the literature.

The incidence of ductal carcinoma in situ has increased with the rise in screening mammography; currently, ductal carcinoma in situ constitutes 20%–25% of all breast cancers, and up to half of them may become invasive. Its early detection is critical in improving the cure rate. Moreover, MRI has higher sensitivity for its detection than mammography. Herein, we report an unusual case of ductal carcinoma in situ presenting as a continuous, serpentine, linear enhancement with regional distribution on MRI.

Neurofibromatosis type 1 (NF1) is a rare neuroectodermal disease that is associated with an increased risk of malignancy. Here, we report a rare case of bilateral breast cancer in a 49-yearold woman with NF1 that presented as a microlobulated oval hypoechoic mass and a complex cystic solid mass on sonography. She underwent bilateral mastectomy. The masses were diagnosed as invasive ductal carcinoma, ductal carcinoma in situ, and a malignant peripheral nerve sheath tumor. We describe the imaging findings, including ultrasonography, CT, and 18F-fluorodeoxyglucose PET.
