Abstract: Objective To discuss the characteristics of ultrasonography on diagnosis of superficial schwannoma. Methods Retrospective analysis of 36 patients ultrasonically diagnosed as superficial schwannoma from January 2014 to June 2015 was done. Results The mass detective rate was 1000%. Among the 36 patients， 24 were confirmed as schwannoma by pathology， and the coincidence rate of ultrasound and pathology was 667%. The shape of schwannoma was round or oval with clear borders. One case was found multiple foci， and the remaining 23 cases showed single lesion. Among the 24 cases， 18 cases showed low echo，and 6 cases showed cystic solid echo. Typical ultrasonographic performance of rat tail was found in 18 cases. According to Adler classification，there were 4 cases in grade 0， 7 in grade Ⅰ， 10 in grade Ⅱ and 3 in grade Ⅱ. ConclusionUltrasonic diagnosis on superficial schwannoma has high diagnostic value with the advantage of easy operation and noninvasion， and is worthy of clinical application.
