US features of mastitis were mild skin thickening and parenchymal edema. Cysts containing internal low-level echoes or septae, or lacking the classical features of simple cysts were called complicated cysts. Well-circumscribed anechoic masses with smooth walls and posterior acoustic enhancement were simple cysts. Hyperechoic breast parenchyma and prominent ducts were considered as physiologic lactational changes. All examinations were performed by 2 radiologists with more than 10 years' experience in US imaging (US systems: Aplio XG, Toshiba, Tokyo, Japan LOGIQ 7, GE Healthcare, Milwaukee, WI, USA).Ī ‘Breast Imaging Reporting and Data System' (BI-RADS) category was assigned to all US examinations on the basis of standardized descriptive criteria published by the American College of Radiology. Patients' electronic medical records were reviewed for the presenting complaint, breast US reports, pathology results if available, and clinical/radiologic follow-up. The mean age of the patients was 31.6 years (range 20-46 years). Our study included 77 actively breastfeeding patients who underwent breast US in our department between February 2012 and March 2017. The Institutional Ethics Committee approved this retrospective study protocol and waived informed consent. The aim of this study is to demonstrate the spectrum of breast US imaging findings in breastfeeding women. Therefore, it is obligatory to be aware of breast lesions seen during lactation, and to be vigilant about malignant features. On the other hand, pregnancy-associated breast cancer is a devastating diagnosis with a poor prognosis and a negative impact on both the mother's and the baby's quality of life. Although some lesions may increase in size, most of the breast lesions detected during lactation are benign. Ultrasound (US) is almost always the first imaging step in lactating women to confirm the presence of a breast lump and to differentiate between cystic and solid lesions. Due to the increased size, nodularity, and sensitivity of the breasts during lactation, physical examination is usually a challenge. Alterations in serum estrogen, progesterone, and prolactin levels are mainly responsible for these structural changes. Radiologists must be aware of malignant US features to avoid delays in the diagnosis of pregnancy-associated breast cancer.įollowing lobular growth and cellular proliferation during pregnancy, the breast transitions to a secretory state during lactation. Conclusion: US can demonstrate or exclude a true mass against the background of a nodular breast parenchyma. Invasive breast cancer was diagnosed in 3 patients. In 13 patients, BI-RADS 3 solid masses were diagnosed. 6 patients had US imaging findings suggestive of mastitis, 5 patients had galactoceles, 1 patient had an abscess, and 1 patient had unilateral hypertrophy without any accompanying lesion. Results: 28 of the 77 patients had normal US findings. All examinations were performed by 2 radiologists. Patients' electronic medical records were reviewed for the presenting complaint, US reports, pathology results if available, and clinical/radiologic follow-up. Methods: 77 breastfeeding patients who underwent breast US in our department between February 2012 and March 2017 were evaluated. We aim to demonstrate the spectrum of US imaging findings in lactating women. Most breast lesions diagnosed in these patients are benign, but the diagnosis of breast cancer is a challenge. When breast problems occur, patients are often referred for an ultrasound (US) scan. Background: Structural changes during lactation make breast physical examination difficult.
