A malignant peripheral nerve sheath tumor (MPNST) is a form of cancer of the connective tissue surrounding peripheral nerves. Given its origin and behavior it is classified as a sarcoma . About half the cases are diagnosed in people with neurofibromatosis ; the lifetime risk for an MPNST in patients with neurofibromatosis type 1 is 8–13%. [ 2 ]
Definitive diagnosis is made by tumor biopsy. [12] Surgery is the most common method of treating peripheral nerve sheath tumors. [11] In malignant tumors, complete resection is the only known curative treatment (with a sufficiently wide margin or even amputation to improve prognosis). [12]
Treating breast cancer with removal of axillary lymph nodes. [9] carrying weight, such as heavy bags, over the shoulder for a prolonged time. [10] Parsonage Turner Syndrome, an autoimmune disease. [11] trauma or infection. [8] Symptoms are often minimal – if symptomatic, a posterior shoulder or scapular burning type of pain may be reported.
A nerve sheath tumor is a type of tumor of the nervous system (nervous system neoplasm) which is made up primarily of the myelin surrounding nerves.Nerve sheath tumors can be benign or malignant, and may affect both the peripheral and central nervous systems.
Wallerian degeneration is an active process of degeneration that results when a nerve fiber is cut or crushed and the part of the axon distal to the injury (which in most cases is farther from the neuron's cell body) degenerates. [1]
Management of brachial or lumbosacral plexopathy depends on the underlying cause. No matter the cause of plexopathy, physical therapy and/or occupational therapy may promote recovery of strength and improve limb function. In the case of a mass lesion causing compression of the brachial or lumbosacral plexus, surgical decompression may be warranted.
The concept behind all of these approaches to the brachial plexus is the existence of a sheath encompassing the neurovascular bundle extending from the deep cervical fascia to slightly beyond the borders of the axilla. [2] Anatomical illustration of the brachial plexus with areas of roots, trunks, divisions and cords marked.
The axillary sheath is a fibrous sheath that encloses the axillary artery and the three cords of the brachial plexus to form the neurovascular bundle. [1] [2] [3] It is surrounded by the axillary fat. [1] [2] It is an extension of the prevertebral fascia of the deep cervical fascia [citation needed] and is continuous with the carotid sheath at ...
