Conventional and functional MR imaging of peripheral nerve sheath tumors: initial experience.
BACKGROUND AND PURPOSE Differentiating benign from malignant peripheral nerve sheath tumors can be very challenging using conventional MR imaging. Our aim was to test the hypothesis that conventional and functional MR imaging can accurately diagnose malignancy in patients with indeterminate peripheral nerve sheath tumors. MATERIALS AND METHODS This institutional review board-approved, Health ...
متن کاملMalignant Peripheral Nerve Sheath Tumors (MPNST)
INTRODUCTION Malignant peripheral nerve sheath tumors (MPNSTs) are sarcomas which originate from peripheral nerves or from cells associated with the nerve sheath, such as Schwann cells, perineural cells, or fibroblasts. Because MPNSTs can arise from multiple cell types, the overall appearance can vary greatly from one case to the next. This can make diagnosis and classification somewhat difficu...
متن کاملHybrid peripheral nerve sheath tumors: A review.
Hybrid peripheral nerve sheath tumors (HPNST) are relatively recently described tumors. With ongoing research, a considerable amount of important findings have been made, much of which has substantial clinical implications. However, a comprehensive review of the whole topic has not been published in the literature so far. In the presented manuscript, the various hybrid tumors are discussed sepa...
متن کاملSurgical management of benign peripheral nerve tumors
Peripheral nerve tumors are rare lesions that can arise anywhere in the body and hence have a myriad of wide differential diagnosis. They commonly present as a non-specific mass which is diagnosed as a peripheral nerve tumor at surgery. While these tumors may initially be referred to a wide variety of surgeons, early recognition of the nature of the lesion and appropriate surgical treatment by ...
متن کاملComparative methylome analysis of benign and malignant peripheral nerve sheath tumors.
Aberrant DNA methylation (DNAm) was first linked to cancer over 25 yr ago. Since then, many studies have associated hypermethylation of tumor suppressor genes and hypomethylation of oncogenes to the tumorigenic process. However, most of these studies have been limited to the analysis of promoters and CpG islands (CGIs). Recently, new technologies for whole-genome DNAm (methylome) analysis have ...
