<i>Introduction</i>:Surgical resection of @entity11 located in the dominant parietal lobe is difficult because this lesion is surrounded by multiple functional areas. Although functional mapping during awake craniotomy is very useful for resection of @entity11 adjacent to eloquent areas, the limited time available makes it difficult to sufficiently evaluate multiple functions, such as language, calculative ability, distinction of right and left sides, and finger recognition. Here, we report a case of @entity3271 , which was successfully treated with a combination of functional mapping using subdural electrodes and monitoring under awake craniotomy for @entity11 . <i>Case presentation</i>:A 32-year-old @entity1 presented with generalized @entity410 . Magnetic resonance imaging revealed a non-enhanced @entity5 in the left angular and supramarginal gyri. In addition, the @entity5 showed high accumulation on 11C-methionine positron emission tomography(PET)( @entity5 /normal brain tissue ratio=3.20). Preparatory mapping using subdural electrodes showed absence of brain function on the @entity5 lesion. Surgical removal was performed using cortical mapping during awake craniotomy with an updated navigation system using intraoperative magnetic resonance imaging(MRI). The @entity5 was resected until @entity2026 was detected by functional monitoring, and the extent of @entity5 resection was 93%. The @entity1 showed transient transcortical @entity2026 and @entity1052 after surgery but eventually recovered. The pathological diagnosis was @entity3271 , and the @entity1 was administered chemo-radiotherapy. The @entity1 has been progression free for more than 2 years. <i>Conclusion</i>:The combination of subdural electrode mapping and monitoring during awake craniotomy is useful in order to achieve preservation of function and extensive resection for @entity11 in the dominant parietal lobe.
