A 56-year-old female presented with transorbital penetrating injury caused by bamboo fragments, which resulted in brain abscess 2 weeks after the injury. Initial computed tomography (CT) of the head did not reveal the foreign bodies. However, follow-up CT demonstrated a well-defined hyperdense abnormality of 1.0 cm length in the left orbit and brain abscess in the left temporal lobe. The lesion corresponding to the hyperdense abnormality on CT appeared isointense on T1-weighted magnetic resonance (MR) imaging and hypointense on T2-weighted MR imaging. The bamboo fragments were surgically removed, and aspiration and continuous drainage were performed for the brain abscess. The postoperative course was uneventful and the patient was transferred to a local hospital with minor neurological deficits. Bamboo foreign bodies may show changes in properties on CT and MR imaging in the subacute stage. Careful radiological examination and follow-up monitoring are required for the correct diagnosis and treatment of such injuries.
一名56岁女性因竹片导致经眶穿透伤，伤后2周出现脑脓肿。头部初始计算机断层扫描（CT）未发现异物。然而，后续CT显示左眼眶有一个边界清晰、长度为1.0 cm的高密度异常，以及左颞叶脑脓肿。CT上对应高密度异常的病变在T1加权磁共振（MR）成像上呈等信号，在T2加权MR成像上呈低信号。手术取出竹片，并对脑脓肿进行穿刺和持续引流。术后病程平稳，患者转至当地医院，遗留轻微神经功能缺损。竹制异物在亚急性期CT和MR成像上可能显示性质变化。对于此类损伤的正确诊断和治疗，需要仔细的影像学检查和随访监测。
