Schwannomas of the larynx: review and computed tomographic scan analysis

Neurogenic tumors consist of schwannomas, neurofibromas, and neurosarcomas that arise from the Schwann cell of a peripheral nerve. Their occurrence in the larynx is rare, with only 115 cases having been reported. Three new cases are presented, the literature is reviewed, and the first computed tomographic (CT) scan of a benign schwannoma of the larynx is demonstrated. The diagnosis and treatment of these tumors and the CT scan analysis are discussed.
