Asymptomatic Case of Cervical Vagal Schwannoma
Financial support and sponsorship Nil.
Abstract
Schwannomas are benign, slow-growing, and encapsulated tumors deriving from the perineural cells located in the nerve sheath. They can arise from any peripheral, cranial, or autonomic nerves and show a predilection for the head and neck region. Extracranial head and neck schwannomas are rare tumors. They may produce secondary symptoms such as nasal obstruction, dysphagia, and hoarseness of voice depending on the location of the tumor. The preoperative diagnosis is difficult. Although preoperative imaging or fine needle aspiration cytology may help to reveal diagnosis, they are inadequate. The definitive diagnosis is made by histopathological examinations.
