结论：我们无法确定胼胝体压部的病灶是由一个单一的病因所致。
Conclusion: We could not identify a single etiologic factor responsible for the lesion in the splenium of the corpus callosum.
测量胼胝体膝部、胼胝体压部和海马的表观扩散系数和各向异性分数。
The appearance diffusion coefficient and the fractional anisotropy were measured for the splenium of the corpus callosum, the genu of the corpus callosum, and the hippocampus.
结果：参数的分析结果显示在胼胝体压部受损的病人和对照组中没有显著性的差异。
Results: the parameters analyzed showed no significant difference between the group of patients with focal lesions in the splenium of the corpus callosum and the control group.
图1：轴位的平扫ct显示对称性的低密度影在颞枕叶脑白质区，需要注意的是病变累及胼胝体的压部。
Figure 1: Axial non contrast CT demonstrates symmetric low attenuation in the temporal-parietal white matter. Note involvement of the splenium of the corpus callosum (red arrows).
DAI最常累及的部位：皮层下白质区、胼胝体(尤其是压部)、放射冠、内囊、脑干背外侧。
The areas most commonly involved in DAI are the subcortical white matter, corpus callosum (especially splenium), corona radiata, internal capsule, and the dorsolateral aspect of the upper brainstem.
结果在23例非出血性胼胝体损伤灶中，膝部损伤5例，体部损伤11例，膝部与体部同时损伤6例，压部1例。
Results The lesions were located at genu in 5 cases, at body in 11 cases, at genu-body in 6 cases, at splenium in 1 case.
