The preoperative diagnosis of peripheral nerve schwannoma was correctly made by US in 3 patients referred to US because of upper extremity palpable mass. The patients complained of no pain and neurological symptoms, except in two cases where there was painful sensation radiating distally during lesion compression. In all cases, sonography demonstrated a sharply delineated hypoechoic homogenous mass with distal acoustic enhancement. The lesions were noted to be in a direct continuity with the cord-like echogenic structure consistent with a nerve. These features enabled a reliable diagnosis of peripheral nerve tumor, most likely schwannoma, to be made. Following a surgical excision, the diagnosis of schwannoma was confirmed by histopathology in all cases.
3例因上肢可触及肿块而接受超声检查的患者，超声均正确作出周围神经鞘瘤的术前诊断。除2例在病变受压时有向远端放射的疼痛感觉外，患者均无疼痛及神经症状。在所有病例中，超声均显示边界清晰的低回声均匀肿块，伴有远端声增强。病变与条索状强回声结构（与神经一致）直接连续。这些特征使得能够可靠地诊断为周围神经肿瘤，很可能是神经鞘瘤。手术切除后，所有病例经组织病理学证实为神经鞘瘤。
