The lack of data regarding the preoperative US features of uterine PEComas is reflected by the frequent misdiagnosis with leiomyomas. We describe the sonographic appearance of a richly vascularized cervical PEComa mimicking a myoma and report the analysis of six additional cases in the literature with a description of their ultrasound features. Most cases involved a single lesion arising from the uterine cervix with a rapid growth pattern, regular margins, heterogeneous echogenicity, absence of shadowing, and moderate\u2010to\u2010rich vascularity.<\/jats:p>","DOI":"10.1002\/jcu.22950","type":"journal-article","created":{"date-parts":[[2020,11,16]],"date-time":"2020-11-16T13:31:32Z","timestamp":1605533492000},"page":"492-497","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Uterine <scp>PEComa<\/scp> initially misdiagnosed as a leiomyoma: Sonographic findings and review of the literature"],"prefix":"10.1002","volume":"49","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3319-8354","authenticated-orcid":false,"given":"Enrico","family":"Fontana","sequence":"first","affiliation":[{"name":"Department of Medical and Surgical Sciences, Gynecology and Human Reproduction Physiopathology Unit, S.
