Schwannomas are benign nerve sheath tumors composed of Schwann cells, which normally produce the insulating myelin sheath covering peripheral, cranial and autonomic nerves. Twenty-five to forty-five percent of all schwannomas occur in the head and neck region, but location of such tumors in the larynx is rarely observed. The present report is aimed at describing a clinical case of laryngeal schwannoma, with emphasis on sonographic findings.
神经鞘瘤是由施万细胞组成的良性神经鞘肿瘤，施万细胞通常产生覆盖周围神经、颅神经和自主神经的绝缘髓鞘。所有神经鞘瘤中有25%至45%发生在头颈部区域，但这种肿瘤在喉部的位置很少见。本报告旨在描述一例喉神经鞘瘤的临床病例，重点介绍超声检查结果。
