Abstract

Cerebral arteriovenous malformations (AVMs) are fairly common and the majority of paediatric patients with this condition also present with intracranial haemorrhage. Two patients who had an incidental finding of an AVM associated with papilloedema are described here. The first was a 13-year-old male who presented after an accidental kick to the eyes. Examination revealed bilateral papilloedema. He gave a 2-year history of intermittent headache. Brain magnetic resonance imaging (MRI) showed an unruptured AVM in the temporal lobe. Lumbar puncture revealed elevated cerebrospinal fluid pressure. Visual acuity and visual fields were normal. He was treated with acetazolamide and improved within a few weeks. He subsequently underwent stereotactic radiosurgery to the AVM. He discontinued acetazolamide due to adverse side effects and there was no recurrence of headache and papilloedema. The second patient was a 14-year-old male who had polyarticular juvenile chronic arthritis and received low-dose steroids and methotrexate. Bilateral papilloedema was discovered during routine ophthalmology surveillance and he was otherwise asymptomatic neurologically. Brain MRI revealed an AVM in the posterior fossa. He had three embolization procedures, which have resulted in significant reduction in lesion size. The papilloedema resolved completely after the first two procedures, and visual acuity and fields remained normal. Here, possible underlying mechanism of raised intracranial pressure and importance of visual assessment in those with AVMs and their management are discussed.
