Objectives The purposes of this study were to report the sonographic features superficial epidermal cysts with an emphasis on characteristic pseudotestis appearance and highlight spectrum ancillary findings. Methods medical records studies all cases surgically proven (n = 42) from January 2005 through December 2009 reviewed. Twenty-six (62%) that appeared sonography as ovoid nodules homogeneous low medium echoes, simulating a testicle, included in group. other 16 (38%) without pattern nonpseudotestis age, sex, lesion size, length width ratio, appearances, frequencies rupture infection compared between groups. Results Epidermal group presented heterogeneously echoic or lobulated had concentric ring target appearance. There no significant differences ratio significantly higher intralesional bright echogenic reflectors filiform anechoic areas than (P < .01). associated features, including posterior acoustic enhancement, dermal attachment, focal protrusion, Conclusions In study, two-thirds sonography, whereas others could be suspected by recognition findings, attachment protrusion distinctive pattern.
