Unusual case of mononeuropathy in child: Intraneural perineurioma of sciatic nerve

Abstract

Intraneural perineurioma is a benign nerve sheath tumor of the perineurium characterized by focal perineural cell proliferation. It is primarily seen in young adults. Early childhood presentation is uncommon. We present this interesting case in a child with overall clinical assessment, nerve conduction tests, and magnetic resonance findings in keeping with intraneural perineurioma of the sciatic nerve. It is essential to recognize this potentially treatable disease entity in the early childhood and exclude other causes of nerve palsy.
