title: Brain scan as an aid in the diagnosis of acoustic neuroma recurrence.
abstract: Brain scans using 99Tcm were performed on 34 patients from whom acoustic neuroma had been removed. The age range was 19 to 66 years at the time of operation. The scans were carried out at intervals up to 13 years postoperatively. There were 4 positive. 3 doubtful, and 26 negative scans. A policy is formulated for periodic scanning as an integral part of the follow-up programme of acoustic neuroma patients.
