CERVICAL AVM PRESENTING AS HYDROCEPHALUS -A CASE REPORT

Dural arteriovenous fistulas (DAVFs) in the cranio-cervical junction are rare but clinically important.

These lesions are often overlooked at cerebral angiography performed to assess SAH and account for a small proportion of angiographically negative SAHs. After managing a case of cervical spinal dural AVM with SAH manifesting as hydrocephalus, we analyzed all cases in the literature to identify features associated with bleeding at presentation
