MR imaging of neurilemoma
arising from the renal hilus.
However, resection of a neurilemoma
with the involved portion of the nerve is almost never required.
For example, the benign neural tumor, neurilemoma
, expresses S-100 as a specific marker, whereas neuro-fibrosarcomas, which sometimes grow out of these benign tumors, do not.
INTRODUCTION: A benign tumour of Schwann cells of the peripheral nerve sheath is called Schwannoma, also called as neurilemoma
Hatziotis JC, Asprides H (1967) Neurilemoma
(schwannoma) of the oral cavity.
Malignant peripheral nerve sheath tumor, which is a sarcoma that arises from a nerve or displays features of neural differentiation, must not be confused with its benign counterpart, neurilemoma
A review of American and European literature till 1975 revealed twelve cases of neurilemoma
, four cases of neurofibromas and one of probable malignant schwannoma.
Neurogenic tumors include neurilemoma
(Schwannoma), neurofibroma, and neuroma, which can also be seen in the mediastinum or lung parenchyma.
She had previously undergone removal of an adenoma from the left thyroid lobe and excision of a neurilemoma
from the right vagus nerve.
Malignant peripheral nerve sheath tumor--also known as neurogenic sarcoma, malignant neurilemoma
, malignant schwannoma, and neurofibrosarcoma--is an uncommon neoplasm that originates in Schwann's cells of the nerve sheath.
A case of neurilemoma
(schwannoma) that mimicked a pleomorphic adenoma (an example of potential pitfall in aspiration cytodiagnosis).
