IMAGING FINDINGS:
Axial post-contrast subtraction image demonstrates two round enhancing masses with irregular margins in the right breast. The mass marked by an arrow shows suspicious ring enhancement. WHY IT MATTERS:

Craniocaudal (CC) views from two consecutive years demonstrate calcifications centrally. The calcifications are identical in morphology and distribution, known as the tattoo sign. WHY IT MATTERS:
Distinguishing Breast Skin Lesions from Superficial Breast Parenchymal Lesions: Diagnostic Criteria, Imaging Characteristics, and Pitfalls (RadioGraphics 2011) IMAGING FINDINGS:
Sonographic image demonstrates an irregular hypoechoic mass with angular margins. Microcalcifications are present within the mass. WHY IT MATTERS:
Sonographically Guided Biopsy of Suspicious Microcalcifications of the Breast: A Pilot Study (AJR 2002) IMAGING FINDINGS:
Standard Craniocaudal (CC) and Mediolateral Oblique (MLO) views of the right breast demonstrate an isodense, oval mass in the lower inner quadrant. The mass has primarily circumscribed margins, but is a new finding compared to prior exams. WHY IT MATTERS:
FURTHER READING: Mucinous Carcinoma of the Breast: MRI Features of Pure and Mixed Forms with Histopathologic Correlation (AJR 2009) IMAGING FINDINGS:
Standard Mediolateral Oblique (MLO) views demonstrate an asymmetrically enlarged lymph node in the left axilla. No abnormality is identified in either breast. Sonographic evaluation of the left axilla demonstrates an abnormal enlarged lymph node with a thickened cortex. The patient reports that she had a COVID vaccination in the left arm two weeks ago.

FURTHER READING: Unilateral axillary Adenopathy in the setting of COVID-19 vaccine (Elsevier 2021) IMAGING FINDINGS:
Standard Craniocaudal (CC) view of the right breast shows an irregular hyperdense mass with spiculated margins in the medial aspect of the breast. Architectural distortion is present in the lateral right breast due to prior lumpectomy. Corresponding ultrasound image demonstrates an irregular hypoechoic mass with posterior acoustic shadowing in the medial breast. WHY IT MATTERS:
Mammary Fibromatosis (AJR 2009) IMAGING FINDINGS:
Standard Craniocaudal (CC) and Mediolateral Oblique (MLO) views of the left breast show a breast composed almost entirely of fat. There is an implanted cardiac device (loop recorder) present within the medial left breast. WHY IT MATTERS:
Radiographic Review of Current Therapeutic and Monitoring Devices in the Chest (RadioGraphics 2018) IMAGING FINDINGS:
Single ultrasound image demonstrates an oval, circumscribed hypoechoic mass. The mass is wider than tall and does not demonstrate any suspicious features. WHY IT MATTERS:
