Pre-Operative Diagnosis of Neurinoma in the Head and Neck Region.

Neurinoma occasionally arises in the head and neck region and pre-operative diagnosis is difficult. In this study we analyzed 7 cases of neurinomas in the head and neck region, and we also discuss the problems of pre-operative diagnosis.CT, MRI, ultrasonography and fine needle aspiration cytology (FNA) were performed and CT, MRI and ultrasonography produced compatible images of the neurinoma. However, FNA that was performed all cases were diagnosed as class I or II. We also report the diagnostic significace of CT, MRI, ultrasonography and FNA.
