In most patients with superficial siderosis of the CNS, the exact source of bleeding remains
unknown because of a lack of objective surgical data. The authors herein describe the case
of a 58-year-old man with superficial siderosis of the CNS. The patient also had spinal CSF
leakage due to a spinal dural defect. Repair surgery for the dural defect was performed

Interventions at the source of bleeding may be the key to a preferable outcome of treatment
for chronic subarachnoid hemorrhage; however, the source is not clear in many cases …
