(A) First craniocerebral computed tomography (CT) scan, taken 3 months prior to admission. This revealed a full ventricular system with a significant bilateral subependymal vascular shadow in the posterior horn of the ventricles. (B) Second craniocerebral CT scan, taken 2 days after admission, which failed to identify any sign of significant ventricular and subarachnoid hemorrhage. (C) Third craniocerebral CT scan, taken 5 days after admission. This revealed mild ventricular and subarachnoid hemorrhage. (D) Angiography of the entire spine revealed a spinal dural arteriovenous fistula involving segments T11-L2.

We performed a CT scan of the skull but there was no evidence of significant intraventricular and subarachnoid hemorrhage (Figure 1B). Urgent head CT scans revealed a minor hemorrhage in the ventricle and subarachnoid space (Figure 1C). T11-L2 segments, which was considered to be a spinal cord arteriovenous malformation (SCAVM-intramedullary) (Figure 1D). The patient subsequently underwent surgery under general anesthesia. A review of the whole cranial and spinal cord angiography revealed that the fistulas had clearly shrunk and that there was no nidus (Figure 1D).
