Neurofibroma of the larynx in neurofibromatosis - Preoperative computed tomography and magnetic resonance imaging

Neurofibromas of the larynx are extremely rare. They occur in association w ith neurofibromatosis less frequently than solitary neurofibromas. However, most laryngeal tumors in neurofibromatosis are neurofibromas. This disorde r has 2 histological subtypes, which require different surgical approaches because of their biological differences. Few cross-sectional imaging studie s have been performed in neurofibroma of the larynx. We describe a 44-year- old man with neurofibromatosis and nonplexiform neurofibroma of the larynx and discuss the role of preoperative computed tomography and magnetic reson ance imaging in this case. The tumor was removed completely using an endola ryngeal approach without an external incision. It was possible to distingui sh subtypes preoperatively on cross-sectional imaging. Magnetic resonance i maging provided more sensitive information in the diagnosis of this tumor t han computed tomography. Preoperative cross-sectional imaging should be per formed to help the surgeon diagnose and choose an appropriate surgical appr oach for this disorder.
