A case is reported of an unusual foreign body, a pencil, penetrating the right temporal lobe through the squamous temporal bone in a fall. Wood has low attenuation coefficients, so that the appropriate CT examination includes multiple window settings to permit accurate assessment of bone fragment displacement as well as recognition of detached wood splinters. CT scanning and early surgery are important steps in the management of these injuries to reduce significantly the overall mortality as well as immediate and long term complications. The necessity for meticulous surgical technique when removing the foreign body is stressed as retained wood can not easily be visualized against the hypodense background due to postoperative changes.
报告了一例不同寻常的异物病例，一支铅笔在一次跌倒中穿过颞鳞部刺入右侧颞叶。木材的衰减系数较低，因此合适的CT检查包括多个窗口设置，以便准确评估骨碎片移位情况以及识别分离的木屑。CT扫描和早期手术是处理这些损伤的重要步骤，可显著降低总体死亡率以及近期和长期并发症。强调了取出异物时采用精细手术技术的必要性，因为术后改变会使残留的木材在低密度背景下不易被看清。
