Sonographic evaluation of interdigital neuromas.
Fifty surgical patients with symptoms suggestive of Morton's neuroma underwent preoperative ultrasound examination of the forefoot using a 7.5 MHz transducer. Fifty-five neuromas were excised. Of these, one neuroma had a ganglion associated with it and five neuromas were recurrent. Four feet had adjacent neuromas. Ultrasound accurately predicted the presence, location and size of the neuromas in 98% of the cases. There were no false positives. In all cases in which a neuroma was predicted by ultrasound, it was confirmed grossly at the time of surgery and later by histological exams. We conclude that ultrasound is an accurate technique in the diagnosis of interdigital neuromas.
