A 61-year-old woman presented with diplopia and headache. The patient had a longstanding history of petrous bone cholesteatoma (PBC) on the left side and had undergone multiple surgeries to address it. Computed tomography (CT) revealed a radiolucent lesion with bony destruction in the left petrous apex. Magnetic resonance imaging of the lesion revealed a hypointense area on T1-weighted images and a hyperintense area on T2-weighted and abnormal diffusion-weighted images. A diagnosis of recurrent petrous apex cholesteatoma was made. The patient was treated by exteriorization using an endoscopic endonasal approach. The patient is in remission and doing well. The ideal treatment of PBC is complete excision, though exteriorization using an endoscopic endonasal approach is considered a second option when excision is not possible.
一位 61 岁女性因复视和头痛就诊。患者左侧有长期的岩骨胆脂瘤（PBC）病史，并接受了多次手术治疗。计算机断层扫描（CT）显示左侧岩骨尖部有一个放射性透亮病变伴骨破坏。病变的磁共振成像显示 T1 加权图像上的低信号区和 T2 加权及异常扩散加权图像上的高信号区。诊断为复发性岩骨尖胆脂瘤。患者采用内镜经鼻入路的外置法进行治疗。患者已缓解，情况良好。PBC 的理想治疗方法是完全切除，但当无法切除时，内镜经鼻入路的外置法被认为是第二选择。
