Superficial siderosis complicated by hydrocephalus: bleeding from the dura mater in the cerebrospinal fluid cavity after brain tumor surgery.
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.



We herein presented a case of superficial siderosis complicated by hydrocephalus 19 years after supratentorial brain tumor resection.



The bleeding source was identified as the dura mater in the intracranial cerebrospinal fluid cavity, and not a recurrent tumor.



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.
