The computed tomographic (CT) appearance of a case of primary meningoencephalitis due to the free living amoeba Naegleria fowleri is presented. The cisterns around and above the midbrain and the subarachnoid spaces were obliterated on precontrast CT. Marked enhancement in these regions was seen after intravenous contrast medium administration. The sulci and adjacent grey matter were also strongly enhanced. The ventricular size was normal. Pathological findings were those of arachnoiditis and invasion of the leptomeninges and brain substance by amoebae, especially at the base of the brain and cerebellum.
本文展示了一例由自由生活阿米巴福氏耐格里变形虫引起的原发性脑膜脑炎的计算机断层扫描（CT）表现。在CT平扫时，中脑周围及上方的脑池和蛛网膜下腔消失。静脉注射造影剂后，这些区域出现明显强化。脑沟和相邻灰质也有强烈强化。脑室大小正常。病理结果显示为蛛网膜炎以及阿米巴对软脑膜和脑实质的侵犯，尤其是在脑底部和小脑部位。
