Abstract

Retrochiasmal optic tract pathology results in contralateral homonymous hemianopia. Hemianopia due to the lesion in anterior optic tract is characteristically non congruous, while that due to pathology in posterior optic radiations and occipital cortex are highly congruous1. An arteriovenous malformation (AVM) of brain is uncommon developmental vascular pathology that may result in significant visual morbidity. The prevalence of brain AVM ranges from 0.01% to 0.5%, generally affecting the population in between 10 – 40 years of age1.
CT and MRI scan of brain are the important noninvasive diagnostic tools for the brain AVM, but cerebral angiography remains the ‘gold standard’ for detecting the micro vascular architecture of the AVM2.
