A 4-year-old boy presented with chopstick penetration into the cerebellum via the temporal squamosa and tentorium cerebelli, which resulted in a cerebellar abscess 1.5 years after the injury. The neuroimaging appearance of the wooden chopstick were unusual, hyperdense on computed tomography, and isointense on T2-weighted and hypointense on T2-weighted magnetic resonance imaging. Abscess aspiration and continuous drainage was performed with real-time intraoperative ultrasound guidance. The chopstick fragment was surgically removed and the patient discharged with minor neurological deficits. Wooden foreign body may show changes in properties after a long period of intraparenchymal retention. Extra care is required to remove wooden foreign bodies because of the high risk of infection.
一名4岁男孩因筷子经颞骨鳞部和小脑幕穿入小脑，受伤1.5年后形成小脑脓肿。木质筷子的神经影像学表现不寻常，计算机断层扫描显示为高密度，T2加权磁共振成像显示等信号，T2加权像上呈低信号。在术中实时超声引导下进行脓肿抽吸和持续引流。手术取出筷子碎片，患者出院时遗留轻微神经功能缺损。木质异物在脑实质内长期存留后可能会出现性质改变。由于感染风险高，取出木质异物需要格外小心。
