An unusual case of a pediatric epidermoid tumor entirely located in the cavernous sinus is reported. A 6-year-old boy presented with left abducens nerve paresis which developed over 2 months. Neuroimaging demonstrated a lesion in the left cavernous sinus. Part of the tumor capsule and the pearly contents were removed by the left pterional approach through Dolenc's anterolateral triangle. No bleeding from the cavernous sinus occurred. The tumor was histologically identified as an epidermoid tumor. Postoperatively, the abducens nerve paresis improved. The presence of dural reflection in the lateral wall of the cavernous sinus and displacement of the intracavernous internal carotid artery are useful indicators for intracavernous lesions.
报告了一例罕见的小儿表皮样肿瘤，肿瘤完全位于海绵窦内。一名6岁男孩出现左侧外展神经麻痹，病程2个月。神经影像学检查显示左侧海绵窦有病变。通过Dolenc前外侧三角经左侧翼点入路切除部分肿瘤包膜和珍珠样内容物。未发生海绵窦出血。肿瘤经组织学鉴定为表皮样肿瘤。术后，外展神经麻痹有所改善。海绵窦外侧壁硬脑膜反折的存在及海绵窦内颈内动脉的移位是海绵窦内病变的有用指标。
