1/7. neurofibroma in the median nerve treated with resection and free nerve transplantation. case reports.The commonest tumours of the peripheral nerves are neurolemomas and neurofibromas, both arising from the nerve sheath. Both tumour types are described. It is established that the neurofibroma becomes malignant in about 10% of cases and that removal involves resection of the nerve. Radical resection is nevertheless recommended and the defect in the nerve may be overcome by free nerve transplantation. Two cases are reported.- - - - - - - - - - ranking = 1keywords = median nerve, median (Clic here for more details about this article) |
2/7. Paramedian transmuscular access to C-3 dumbbell-type neurofibroma without paravertebral muscle dissection from the spinous process or facetectomy. Technical note.The authors devised a paramedian transmuscular approach to the C2-3 facet joint that enabled total removal of C-3 dumbbell-type neurofibroma; dissection of the paravertebral muscles from the spinous process was not required and the facet joint was preserved. Only splitting or retraction of the paravertebral muscles was necessary. The anatomical features and procedures involved in muscle splitting are described.- - - - - - - - - - ranking = 0.0060573236394828keywords = median (Clic here for more details about this article) |
3/7. Nerve tumors of the hand and forearm.Peripheral nerve tumors comprise less than 5% of all tumors of the hand. The most common solitary nerve tumor is the neurilemmoma, which arises from the neural sheath, is well encapsulated, minimally symptomatic, and may be surgically enucleated without producing a neurological deficit. Neurofibromas may be solitary, multiple, or associated with von Recklinghausen's disease. They are usually centrally placed with nerve fibers traversing the tumor mass making it more difficult to remove the tumor without producing permanent neurological damage. Malignant tumors include neurofibrosarcomas which often are very aggressive, requiring wide excision or amputation, and the rare neuroepitheliomas. Reported nerve tumors, intraneural in location but nonneural in origin, include fibrofatty infiltration of the median and digital nerves, intraneural lipoma, hemangioma, and ganglion cysts. These lesions may be treated by decompression or excision, depending on the nature of the tumor. Four unusual cases are described.- - - - - - - - - - ranking = 0.0012114647278966keywords = median (Clic here for more details about this article) |
4/7. A case of neurofibroma of the palmar cutaneous branch of the median nerve.This case report describes a previously unreported entity, a neurofibroma of the palmar cutaneous branch of the median nerve. The lesion presented as a palmar mass with an overlying abnormality of the skin. Treatment consisted of excision of the lesion. Infiltration of the terminal branches of the nerve by the tumour prevented nerve reconstruction but provided a previously unknown diagnostic clue: fibrosis of an area of skin innervated by the involved nerve, which had the appearance of a callosity.- - - - - - - - - - ranking = 1.25keywords = median nerve, median (Clic here for more details about this article) |
5/7. Resection of the median nerve without sequelae (resection of 15 cm due to neurofibroma).A case of neurofibroma of the median nerve at the wrist is reported. An operation to resect 15 cm of the nerve was performed; no transplant was substituted. No motor or sensory paralysis was noted, either directly after the operation or at follow up after nine years. Injection of procaine into the ulnar nerve at the epitrochlear groove demonstrated complete compensation, by means of anastomoses between the two nerves at the upper third of the forearm. It is assumed that the type of lesion (circumscribed neurofibromatosis) beginning in infancy or childhood, had some influence in giving rise to this substitution.- - - - - - - - - - ranking = 1.25keywords = median nerve, median (Clic here for more details about this article) |
6/7. Malignant transformation in a plexiform neurofibroma of the median nerve.A malignant schwannoma of the median nerve occurred in a 27-year-old woman with multiple neurofibromatosis (von Recklinghausen's disease). A growth had been present at the left wrist since birth and was partially excised at the age of 10 years. The patient refused an amputation and radical local excision did not control this highly malignant tumor.- - - - - - - - - - ranking = 1.25keywords = median nerve, median (Clic here for more details about this article) |
7/7. CT morphology of a median nerve neurilemmoma at the arm. Case report and review.Computed tomography was performed in a patient with a median nerve tumor at the arm, histologically confirmed as neurilemmoma. neurilemmoma was a slightly hypodense, solid tumor with no vascular contrast enhancement. To our knowledge this is the first CT description of a median nerve neurilemmoma at the arm. According to our experience and to previous literature, CT gives useful information regarding extent, anatomic location, size and relationship of peripheral nerve neoplasm to surrounding structures and may be an useful tool for evaluation arm nerve mass and for appropriate planning of surgical therapy.- - - - - - - - - - ranking = 1.5keywords = median nerve, median (Clic here for more details about this article) |
