Peripheral Nerve Tumours

Usg, CT and MRI are the main standbys in imaging the peripheral nerve tumours. The differential for peripheral nerve tumours must be kept in mind when imaging.Neurilemmomas are solitary, encapsulated with the nerve at the periphery.Neurofibromas have no capsule and the nerve is central. Plexiform neurofibroma has a bag of worms appearance. Malignant schwanoma is seen in 10% of cases with previous radiation and 50% of cases of Von Reklinghausens disease. Truamatic neuroma is the stump or amputation neuroma.Mortons neuroma is fibrosis and degeneration of plantar digiral nerves.Intraneural ganglion invades the nerve and may be associated with atrophy of muscles in the peroneal compartment.
