Neurinoma originating from the recurrent nerve: Report of a case

Schwannoma is an uncommon, peripheral nerve sheath tumor of the neck that can occur either as an isolated lesion or multiple lesions. Multiple schwannomas, as seen in neurofibromatosis, occur less frequently. The rare occurrence and poorly defined symptoms of these tumors often make their preoperative diagnosis difficult. This report describes an unusual case of recurrent nerve Schwannoma which was successfully identified by color Doppler sonography.
