Intracranial arteriovenous malformation

Intracranial arteriovenous malformation presenting with papilloedema

Authors: Hayton T, Gan P, Sadalage G, Burdon M.

Intracranial arteriovenous malformations (AVM) typically present clinically with haemorrhage, seizures or focal neurological deficit. AVM do not usually have a substantial mass effect or cause raised intracranial pressure. Rarely shunting of arterial blood into the venous system can cause raised venous pressure and consequently raised CSF pressure. The case described here is of a 37 year old man with an AVM who presented with headache and papilloedema secondary to raised CSF pressure. Following partial embolisation, to reduce fistulous flow, and stereotactic radiosurgery (SRS), to reduce the size of the AVM, both the headache and papilloedema resolved.
