Median nerve schwannoma: A rare case report

Abstract

Schwannomas are also known as neurilemmomas which usually originate from Schwann cells located in the peripheralnerve sheaths. They usually occur in the age group of 20 to 70 years. They account for 5% of all tumors in the upperextremity. Schwannomas are usually solitary, encapsulated, and homogeneous masses and present with slowly growingmasses, sometimes associated with pain and paresthesia. X-ray, magnetic resonance imaging (MRI), and ultrasonography(USG) are helpful in the diagnosis; however, the definite diagnosis requires histopathology. Herein, we report a rare casediagnosed as a schwannoma of the median nerve in a 59-year-old male patient. We discuss the clinical presentation, imaging,surgical findings, and functional outcomes in the light of literature data. This tumor has a good prognosis with a lowrecurrence rate and potential for malignant transformation. The surgical removal is usually curative.
