The cause of the recurrent SAH is determined on imaging in only 50% of cases (3) and includes dural pathology, postsurgical CSF cavity with neovascularity, bleeding central nervous system (CNS) tumours (ependymoma, oligodendroglioma and astrocytoma), vascular malformations (arteriovenous malformations and cavernous malformation near the brain's surface), aneurysms, and in the spinal cord--tumours, arteriovenous malformations and traumatic nerve root avulsion.
