The following US features were assessed: size, border, echogenicity, homogeneity, intralesional cystic necrosis, presence of septa, intralesional calcification, posterior acoustic enhancement and blood supply.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Of the 15 tumors, seven (46.7%) were located on the left side, and the remaining eight (53.3%) on the right side. The most frequent US appearance of adrenal schwannoma was a single, well\u2010defined and isoechoic mass. The internal echotexture was homogeneous in 2 cases, and heterogeneous in 13 cases, with intralesional cystic areas (<jats:italic>n<\/jats:italic>\u2009=\u200911), septa (<jats:italic>n<\/jats:italic>\u2009=\u200910) or calcifications (<jats:italic>n<\/jats:italic>\u2009=\u20096). Posterior acoustic enhancement was seen in 12 of the 15 cases (80%).

These appearances should suggest the diagnosis of adrenal schwannomas. Nevertheless, additional information from laboratory tests and CT or MR imaging may be required to avoid unnecessary surgery.<\/jats:p><\/jats:sec>","DOI":"10.1002\/jcu.22644","type":"journal-article","created":{"date-parts":[[2018,10,5]],"date-time":"2018-10-05T19:02:12Z","timestamp":1538766132000},"page":"3-8","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Sonographic
