Abstract:
Peripheral nerve sheath tumors (PNST) include schwannoma, neurofibroma and malignant peripheral sheath tumors. All neurogenic tumors share the same imaging characteristics, including fusiform shape, low attenuation on CT, fascicular sign, split fat sign and associated muscle atrophy. The aim of this article is to give a comprehensive overview of peripheral nerve tumors and to discuss the imaging characteristics that distinguish these masses.
