Gas CT cisternography is a reliable examination for the detection of small acoustic neuromas. False-positive or equivocal findings do result, however, from a small number of these examinations. In this case report inadvertent subdural injection of gas caused diagnostic difficulties.
气体脑池造影是检测小型听神经瘤的可靠检查方法。然而,少数此类检查确实会出现假阳性或不明确的结果。在本病例报告中,无意中硬膜下注入气体导致了诊断困难。
