Case Discussion
Morton neuromas are focal areas of symptomatic perineural fibrosis around a plantar digital nerve of the foot. The abnormality is non-neoplastic and does not represent a true neuroma.
It may more correctly be known as Morton’s metatarsalgia. The condition is thought to be due to chronic entrapment of the nerve by the inter-metatarsal ligament.
