Mortons neuroma

Cause, clinical and ultrasound findings

• Fibrous tissue around the interdigital nerve may result from friction from wearing high heels, abnormal loading, etc.

• The patient has stabbing or aching pain and a tender area at the interdigital space on pressure (Tinel test).

• Ultrasound findings are a hypoechoic lesion (neuroma) at the intermetatarsal space, with or without associated bursitis. On pressure, the bursitis is shifted away and the neuroma is more evident.
