that arise from the nerve sheaths of peripheral nerves.

predilection for the head, the neck, and the flexor surfaces of the
upper and lower extremities. Histopathology is the most definitive
way to confirm the nature of these lesion, however well planned
CT scan will adequate pre-operative information for surgical planning.
Though MRI is the gold standard and investigation of choice

pre-operative evaluation of these lesions.
