Abstract

Background: Cervical schwannoma is a rare and benign tumor exclusively developed from the cell of Schwann that rarely involves the vagus nerve. Methods: We reported two illustrative cases and a brief literature review. Both patients presented with a history of painless palpable mass in the cervical region. Results: In both cases the lesions were diagnosed by means of imaging studies and were totally resected. Surgical findings and histopathology confirmed the diagnosis of vagus nerve schwannoma. There was no recurrence at five years of follow-up. In one case there was dysphonia that solved within six months after the surgery. Conclusion: Vagus nerve schwannomas are rare benign tumors. The enucleation technique is used to obtain the most functional preservation and complete excision without permanent deficit is possible even with the occurrence of large lesions.
