Application of multiple imaging modalities is helpful for the preoperative surgical planning, and technical advances in percutaneous endoscopy would render the surgical approach even less invasive. Case presentation: We present a 60-year-old female patient with a transorbital penetrating injury (TPI) caused by a bamboo stick in her right eye. The bamboo stick was initially pulled out at the emergency room but, 1 month later, massive bleeding from her nose and mouth occurred. CT and CTA revealed a foreign body in the right orbito-cranial region and a traumatic aneurysm at the right internal carotid artery. Endovascular embolization was first delivered to treat the aneurysm, and the remains of the bamboo stick were completely removed with a percutaneous endoscope. The patient was discharged 1 week later. Conclusions: A careful preoperative examination by multiple imaging modalities, e.g., CT, MRI, and DSA are essential for the correct diagnosis and surgical planning for the patient with a TPI. We minimised the associated risks of vascular and nervous injuries during foreign body removal by sequential application of the endovascular intervention and percutaneous endoscopic technique.展开更多
