Computed tomography of acoustic neuroma

ABSTRACT

Despite a variety of clinical testes of acoustic tumour, a definitive diagnosis can only be made by radiology. Evaluating the IAM by plain X-ray tomography is the essential primary examination. Computed tomography with intravenous contrast is a necessary prelude to air meatography as large tumours are not satisfactorily demonstrated by meatogaphy as large tumours are not satisfactorily demonstrated by that technique and there may be risk for obstructive hydrocephalus. Seven cases are included in this study. The results of examination by CT were analysed as regard the side, site and enhancement of the lesion in addition to the sensitivity of this modality in detection localization and definition of the lesion
