Orbital injuries may be associated with the presence of foreign bodies in which long retention leads to damages such as loss of vision or cerebral abscess. We present the case of a 21-year-old male patient that developed ptosis, limitation of movements and an inflammatory reaction in the right eye after being hit by a tree branch. A CT scan of the orbits revealed an increased density in the right orbital cone. After the neurosurgical approach for the removal of the foreign body, a wooden fragment measuring 2.0x0.3 cm, the patient had a good outcome without visual deficits, ptosis regression and resolution of the inflammatory process. The postoperative CT scan didn't identify any remaining foreign body fragment. This case calls attention to the fact that the wooden splinter presented on CT scan with high density (136 HU) two months after the trauma and was removed by a supraorbital craniotomy.
眼眶损伤可能与异物存在有关，异物长期留存会导致如视力丧失或脑脓肿等损害。我们报告一例21岁男性患者，其被树枝击中后右眼出现上睑下垂、活动受限及炎症反应。眼眶CT扫描显示右眼眶圆锥密度增加。经神经外科手术取出一块2.0×0.3厘米的木质碎片异物后，患者预后良好，无视力缺损，上睑下垂消退，炎症过程得以解决。术后CT扫描未发现任何残留异物碎片。该病例提醒注意，创伤两个月后CT扫描显示木质碎片呈高密度（136 HU），并通过眶上开颅术取出。
