title: Role of sonography in the preoperative assessment of neurilemmoma.
abstract: This case report illustrates the role of high-resolution sonography in the preoperative assessment of a neurilemmoma of the median nerve in the forearm. Sonography identified the 3-dimensional localization of the nerve tumor its origin from a nerve fascicle, and its relationship with noninvolved nerve fascicles, facilitating the surgeon's approach to preserve noninvolved fascicles.
