In adults, left temporal lobe pathology is typically associated with verbal memory deficits, whereas right temporal lobe pathology is thought to produce visual memory deficits in right-handed individuals. However, in children and adolescents with temporal lobe pathology, conclusions regarding material specificity of memory deficits remain unclear. The goal of the present case series is to examine the profile of verbal and visual memory impairment in children with temporal lobe tumors. Three patients with identified right temporal tumors and three patients with left temporal tumors are included. The Wide Range Assessment of Memory and Learning-Second Edition (WRAML-2) was administered as part of a larger neuropsychological battery. As anticipated, participants with right temporal lesions showed impaired visual memory relative to intact verbal memory. Interestingly, although the discrepancies between verbal and visual indices were less extreme, those with left temporal lesions showed a similar memory profile. These seemingly counterintuitive findings among left temporal tumor patients likely reflect less hemispheric specialization in children in comparison to adults and the fact that early developmental lesions in the left hemisphere may lead to functional reorganization of language-based skills.
在成年人中，左侧颞叶病变通常与言语记忆缺陷相关，而右侧颞叶病变被认为会在右利手个体中导致视觉记忆缺陷。然而，在患有颞叶病变的儿童和青少年中，关于记忆缺陷的材料特异性的结论仍不明确。本病例系列的目的是研究患有颞叶肿瘤的儿童的言语和视觉记忆损害情况。纳入了三名确诊为右侧颞叶肿瘤的患者和三名左侧颞叶肿瘤的患者。作为一个更大的神经心理学测试组合的一部分，实施了《广泛记忆与学习评估第二版》（WRAML - 2）。正如预期的那样，右侧颞叶病变的参与者相对于完好的言语记忆表现出视觉记忆受损。有趣的是，尽管言语和视觉指标之间的差异不那么极端，但左侧颞叶病变的参与者也表现出类似的记忆模式。左侧颞叶肿瘤患者中这些看似违反直觉的发现可能反映出与成年人相比，儿童的半球特化程度较低，以及左半球早期发育性病变可能导致基于语言的技能发生功能重组这一事实。
