41 year old female status post right partial mastectomy and sentinel lymph node biopsy needs MRI due to dense breasts for further evaluation. There is heterogeneous amount of fibroglandular tissue in both breasts.Mild parenchymal enhancement is noted bilaterally. Thin rimmed enhancing seroma cavity measuring 19 x 12 x 15 mm (AP X ML X CC) is identified in the right breast 12:00 position. No abnormal enhancement is seen in right breast. Oval progressively enhancing mass with smooth margins is noted in the left breast 4:00 position, mid depth that measures 8 x 5 x 6 mm (AP X ML X CC) which is most likely benign but not easily identified on the mammogram in retrospect. No abnormal axillary lymph nodes are identified in either axillary region. Post surgical changes in the right axillary region. Small high T2 signal lesion in right lobe of liver is most likely a cyst of a hemangioma.
Post surgical changes in right breast and axillary region. Incidentally noted 8 mm oval enhancing mass is seen in the left breast 4:00 position for which MRI directed ultrasound is recommended. If ultrasound is negative, 6 month follow up MRI is recommended to confirm stability of this most likely benign lesion. BIRADS: 0 - INCOMPLETE; Need additional imaging evaluationRECOMMENDATION: E - Additional Mammo/Ultrasound Workup Required.
