    BACKGROUND: Subarachnoid hemorrhage (SAH) occasionally originates from extracranial arteries, and SAH caused by cervical trauma is even rarer.

    CASE REPORT: A 17-year-old male patient was admitted to our emergency department aftera bike accident; he was drowsy and showed left hemiparesis. Initial computed tomography (CT) of the brain showed SAH into the cervicomedullary cistern. A 4-hour follow-up brain CT revealed heavy bleeding into the basal cistern. Because CT angiography did not show any vascular injury, we performed imaging studies of the cervical spine. Magnetic resonance imaging revealed a blood clot located ventral to the C4-C5 level of the spinal cord without any flow void. The patient's condition deteriorated over time, and he was accordingly referred for surgery. Intraoperatively, a thick subarachnoid hematoma ventral to the spinal cord was observed. The hematoma was removed and hemostasis by bipolar cauterization was performed for bleeding from a small branch of the anterior spinal artery. Postoperatively, the weakness of the lower extremity improved considerably.

    CONCLUSION: In young adult patients with SAH of unexplained origin, we suggest that the cervical region be considered as the bleeding focus; in such cases, surgical evacuation of bleeding can save some patients.
