CT morphology of a median nerve neurilemmoma at the arm. Case report and review.

: Computed tomography was performed in a patient with a median nerve tumor at the arm, histologically confirmed as neurilemmoma. Neurilemmoma was a slightly hypodense, solid tumor with no vascular contrast enhancement. To our knowledge this is the first CT description of a median nerve neurilemmoma at the arm. According to our experience and to previous literature, CT gives useful information regarding extent, anatomic location, size and relationship of peripheral nerve neoplasm to surrounding structures and may be an useful tool for evaluation arm nerve mass and for appropriate planning of surgical therapy.
