Cervical sympathetic schwannoma is relatively rare, In our three cases, each case presented with a cervical swelling, but no neurological signs. Findings of ultra-sonography, CT scan, and MR imaging revealed the tumors as schwannoma, which suspected arising from the vagus nerve or from the cervical sympathetic nerve. We performed inter-capsular resection of the tumor. All patient showed Horner's symptoms after the operation, which proved the tumors arising from the cervical sympathetic nerve. The symptoms of two cases have improved, and we thought the inter-capsular resection was successful.
