Present a classification of peripheral nerve tumors Illustratively describe the spectrum of involvement on radiological imaging. Supplement the most spectacular cases with intraoperative findings for better understanding of correlation between imaging and anatomical features.
Peripheral nerve tumors (PNTs) is a heterogeneous group of nerve neoplasms.
They can be classified into two large groups: benign and malignant,
both of which include subcategories.
Benign PNTs are most common nerve sheath neoplasms such as schwannomas.
a group of non-neoplastic nerve tumors such as neuromas and rare neoplasms of non-neural sheath,
intraneural ganglion cysts also fall under this category.
Malignant PNTs can be divided into two categories: nerve sheath...
Findings and procedure details
To understand the variety and also etiology of PNTs a detailed classification is presented in Table 1.
it is important to note that many of the entities included in the classification are histological types and cannot be differentiated only radiologically.
Although there are no imaging criteria that can reliably distinguish malignant from benign lesions,
some imaging findings might help to differentiate benign tumors from malignant.
These findings are discussed below. BENIGN...
PNT is a common group of neoplasms,
radiologists must be alert in order to differentiate between its malignant or benign origin.
US and MRI are used for detection,
differentiation and follow up of this pathology.
