PURPOSE
Our goal was to determine whether the size of the lateral ventricle influences asymmetry of the fornix in patients with mesial temporal sclerosis.
METHODS
The cross-sectional area of the lateral ventricle was measured along with the thickness of the fornix in 18 patients with pathologically proved mesial temporal sclerosis. Two additional patients with ventricular asymmetry and seizures but without mesial sclerosis were also studied.
RESULTS
Ten of 18 patients with mesial temporal sclerosis had equally sized ventricular areas or less than a 25% difference between the two sides. In seven of these 10, the left and right fornices were equal; in the other three patients, the fornix was thinner on the side of mesial sclerosis. Among the eight patients with ventricular area differences greater than 25%, the larger ventricle was on the side of mesial sclerosis in five cases. In all of these, the ipsilateral fornix was thinner. In three of eight cases, the contralateral ventricle was larger; in two, the left and right fornix were equal; and in one, the fornix contralateral to the side of mesial sclerosis was smaller. The greatest difference in fornix thickness was noted in patients with ventricular asymmetry greater than 40%, regardless of side or presence of mesial temporal sclerosis.
CONCLUSION
The size of the lateral ventricle may influence the apparent thickness of the fornix.
目的
我们的目标是确定内侧颞叶硬化症患者侧脑室的大小是否会影响穹窿的不对称性。
方法
对18例经病理证实为内侧颞叶硬化症的患者测量了侧脑室的横截面积以及穹窿的厚度。还研究了另外2例有脑室不对称和癫痫发作但无内侧硬化症的患者。
结果
18例内侧颞叶硬化症患者中有10例两侧脑室面积相等或两侧差异小于25%。在这10例中的7例中，左右穹窿相等；在另外3例患者中，内侧硬化症一侧的穹窿较薄。在脑室面积差异大于25%的8例患者中，5例较大的脑室位于内侧硬化症一侧。在所有这些病例中，同侧穹窿较薄。在8例中的3例中，对侧脑室较大；2例中，左右穹窿相等；1例中，内侧硬化症一侧对侧的穹窿较小。无论内侧颞叶硬化症的侧别或是否存在，在脑室不对称大于40%的患者中，穹窿厚度的差异最大。
结论
侧脑室的大小可能会影响穹窿的表观厚度。
