Abstract:
Objective To investigate the ultrasonic features and differential diagnosis of superficial neurilemmoma ,and improve diagnostic accuracy of superficial neurilemmoma by ultrasound .Methods Retrospectively analyse the ultrasonic findings of 51 ca-ses ,which confirmed for superficial neurilemmoma by pathology ,and analyse the misdiagnosis reason from the aspects of size , shape ,boundary ,internal echo ,blood flow signals .Results Superficial neurilemmoma had some characteristics in the shape ,bound-ary ,internal echo ,blood flow signals and so on .However ,the key point to differentiate it from other diseases was to identify the re-lationship with peripheral nerve .In this study ,the coincidence rate of ultrasonoic diagnosis with pathologic diagnosis was 78 .4% . Conclusion Superficial neurilemmoma have some similarity with neurofibroma or sebaceous cyst on ultrasonographic images .When making diagnosis ,especial attention should be paid to identify the relationship of neurilemmoma with peripheral nerve .
