Owing to its extremely low incidence, the imaging characteristics of EMC have not been fully described, particularly with regard to emerging ultrasound techniques, such as shear-wave elastography (SWE) and contrast-enhanced ultrasound (CEUS). Herein, we report the case of a 70-year-old woman with breast EMC. The multimodal imaging findings, including digital mammography, computed tomography (CT), magnetic resonance imaging (MRI), conventional ultrasound (grayscale and color Doppler), SWE, and CEUS, are systematically presented and analyzed in correlation with the pathological findings. This report aims to improve clinical understanding of the imaging features of EMC.<\/jats:p>","DOI":"10.3389\/fonc.2026.1845855","type":"journal-article","created":{"date-parts":[[2026,7,1]],"date-time":"2026-07-01T09:44:23Z","timestamp":1782899063000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Multimodal imaging features of primary breast epithelial\u2013myoepithelial carcinoma: a case report and literature review"],"prefix":"10.3389","volume":"16","author":[{"given":"Peilin","family":"Sha","sequence":"first","affiliation":[{"name":"The Third Affiliated Hospital of Beijing University of Chinese Medicine","place":["Beijing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yunhao","family":"Luo","sequence":"additional","affiliation":[{"name":"School of Medical and Life Sciences, Chengdu University of Traditional Chinese Medicine","place":["Chengdu, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiangzhu","family":"Wang","sequence":"additional","affiliation":[{"name":"The Third Affiliated Hospital of Beijing University of Chinese Medicine","place":["Beijing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yanhong","family":"An","sequence":"additional","affiliation":[{"name":"Dongzhimen Hospital, Beijing University of Chinese Medicine","place":["Beijing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jia","family":"Jia","sequence":"additional","affiliation":[{"name":"Beijing Chaoyang Hospital, Capital Medical University","place":["Beijing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xue","family":"Shi","sequence":"additional","affiliation":[{"name":"Beijing Chaoyang Hospital, Capital Medical University","place":["Beijing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xin","family":"Li","sequence":"additional","affiliation":[{"name":"Beijing Chaoyang Hospital, Capital Medical University","place":["Beijing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mengke","family":"Xu","sequence":"additional","affiliation":[{"name":"Beijing Chaoyang Hospital, Capital Medical University","place":["Beijing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huiyu","family":"Ge","sequence":"additional","affiliation":[{"name":"Beijing Chaoyang Hospital, Capital Medical University","place":["Beijing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zexing","family":"Yu","sequence":"additional","affiliation":[{"name":"Beijing Chaoyang Hospital, Capital Medical University","place":["Beijing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,7,1]]},"reference":[{"key":"B1","doi-asserted-by":"crossref","first-page":"161","DOI":"10.1007\/978-3-662-30514-0_3","article-title":"The myothelia (myoepithelial cells).
