Cervical vagal schwannoma is an extremely rare neoplasm. Middle aged people are usually affected. These tumors usually present as asymptomatic masses. These tumors are almost always benign. Preoperative diagnosis of these lesions is important due to the morbidity associated with its excision. Preoperative tissue diagnosis is not accurate. The imaging modality can be done to assess the extent and for planning the treatment. Surgical excision with preservation of neural origin is the treatment option. Giant vagal schwannomas are extremely rare. Only one case has been reported in the literature till date. There has no reported case of extensive vagal schwannoma from skull base to the mediastinum. Here, we describe the asymptomatic presentation of an unusual appearing giant cervical vagal schwannoma with an extension from skull base to the mediastinum.
