Sonographic Characteristics of Peripheral Nerve Sheath Tumors
Schwannomas (or neurilemmomas) and neurofibromas are the two most common types of peripheral nerve sheath tumors, and they are difficult to distinguish with imaging. Neurofibromas may present as a solitary mass or as multiple masses as part of neurofibromatosis.
