Tomodensitometry allowed us to discover smaller and smaller tumors in the cistern and even in the internal auditory canal. We report 5 cases, amongst others, where the tumor is visible in the canal and we show the conditions which are necessary to make the diagnosis. Nevertheless, lipiode meatocisternography is well tolerated if we use between 0.6 and 1.5 ml of oil, and often necessary to confirm the diagnosis of a neuroma. We first use tomodensitometry when the symptoms could be due to a neuroma or another tumor. When the syndrome is characteristic, limited to the contents of the internal auditory canal, we often do the meatocisternography straight away, because in a single examination we know that there is or is not a tumor. We can also check the same time the opposite side.
计算机断层扫描使我们能够发现脑池甚至内听道内越来越小的肿瘤。我们报告了5例等情况，其中肿瘤在耳道内可见，并且我们展示了做出诊断所需的条件。然而，如果我们使用0.6至1.5毫升的油，碘油脑池造影耐受性良好，并且通常对于确诊神经瘤是必要的。当症状可能由神经瘤或其他肿瘤引起时，我们首先使用计算机断层扫描。当综合征具有特征性，仅限于内听道内容物时，我们通常会直接进行脑池造影，因为在一次检查中我们就能知道是否存在肿瘤。我们还可以同时检查对侧。
