Background: In most patients with superficial siderosis of the central nervous system, the exact source of bleeding remains unknown and a treatment has not yet been established.
Methods: We herein presented a case of superficial siderosis complicated by hydrocephalus 19 years after supratentorial brain tumor resection.
Results: The bleeding source was identified as the dura mater in the intracranial cerebrospinal fluid cavity, and not a recurrent tumor.
Conclusion: Chronic intracranial bleeding from the dura mater was successfully arrested by replacement of the dura mater with the autologous fascia of the thigh, and hydrocephalus was treated with endoscopic surgery.
