We have found variability in the sonographic appearance of peripheral nerve sheath tumors. The purpose of this study was to characterize the sonographic appearances of pathologically proven peripheral nerve sheath tumors.
Peripheral nerve sheath tumors are often hypoechoic with posterior acoustic enhancement and so may simulate a ganglion cyst. The presence of intrinsic blood flow on color Doppler sonography and peripheral nerve continuity suggests the diagnosis of peripheral nerve sheath tumor. Sonography cannot reliably distinguish neurofibromas from schwannomas.
我们发现周围神经鞘瘤的超声表现存在变异性。本研究的目的是描述经病理证实的周围神经鞘瘤的超声表现。
周围神经鞘瘤通常为低回声，后方伴有声增强，因此可能类似腱鞘囊肿。彩色多普勒超声显示内部血流信号以及周围神经连续性提示周围神经鞘瘤的诊断。超声不能可靠地区分神经纤维瘤和神经鞘瘤。
