Abstract
The authors report a rare case of a dumbbell-shaped cervical neurinoma that extended to the anterior cervical region in a 51-year-old man. The subject was admitted to hospital because he had noted a right anterior cervical tumor and hypesthesia that had developed in his right hand. Subsequent MR imaging revealed a dumbbell-shaped tumor at the C1-2 level that exteded to the right anterior cervical region. Further, an angiogram showed a stained tumor that was being fed by the right vertebral artery. Total removal of the tumor was successfully accomplished by a two-stage operation : first, using a posterior approach, the intraspinal and laterally extended portions of the tumor were extirpated, then, after an interval, using an anterior approach, the anterior portion of the tumor was removed. After the first operation, the patient was confined to bed for only a week, and later, he had to wear a Philadelphia poly-neck collar whenever ambulatory for one month.
