One hundred consecutive patients with symptoms suggestive of Morton neuroma were examined with sonography, and 134 intermetatarsal masses were demonstrated. Forty-five patients underwent surgical exploration, which revealed Morton neuromas. The typical sonographic appearance is that of an ovoid, hypoechoic mass oriented parallel to the long axis of the metatarsals. Most masses were between the second and third or third and fourth metatarsals and seemed to produce symptoms when reaching a diameter of 5 mm.
对100例疑似莫顿神经瘤的患者进行超声检查，共发现134个跖间肿物。45例患者接受了手术探查，结果显示为莫顿神经瘤。典型的超声表现为椭圆形、低回声肿物，其长轴与跖骨长轴平行。大多数肿物位于第二和第三或第三和第四跖骨之间，直径达5mm时似乎会引发症状。
