Twenty patients underwent only US; 7 patients underwent only MRI; and 2 patients underwent US and MRI. Clinical data and histopathologic specimens were reviewed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>There were 19 women and 10 men. The mean patient age was 48.9 years (range, 23\u201380 years). On US, angioleiomyomas were located primarily in the subcutaneous fat layer (n\u2009=\u200920 [91%]), were oval (n\u2009=\u200917 [77%]), had well\u2010circumscribed margins (n\u2009=\u200922 [100%]), had hypoechoic protrusions on one or both ends (n\u2009=\u20099 [41%]), had a homogeneous echo texture (n\u2009=\u200917 [ 77%]), had posterior acoustic enhancement (n\u2009=\u200920 [91%]), and had color Doppler flow (n\u2009=\u200920 [91%]). On MRI, the masses showed heterogeneous enhancement (n\u2009=\u20097 [88%]) and enhancing structures on one or both ends (n\u2009=\u20094 [50%]) on contrast\u2010enhanced T1\u2010weighted images.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Angioleiomyoma of the extremities is usually a well\u2010circumscribed oval mass with a homogeneous echo texture and occasionally hypoechoic protrusions on US and shows heterogeneous enhancement with occasionally enhancing structures on one or both ends of the mass on MRI. Therefore, it should be included in the differential diagnosis of a soft tissue mass that has protruding structures from one or both ends.<\/jats:p><\/jats:sec>","DOI":"10.1002\/jum.14798","type":"journal-article","created":{"date-parts":[[2018,9,12]],"date-time":"2018-09-12T16:41:19Z","timestamp":1536770479000},"page":"1201-1208","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["Angioleiomyoma
