Abstract
A case of arteriovenous malformation in the left occipital lobe with purely left external carotid contribution is reported in this paper. The patient was a 60-year-old male, who complained of right hand sensory disturbance and headache. CT scan revealed a heterogenous low-density area in the left occipital lobe. Intravenous DSA and conventional carotid angiography showed the arteriovenous malformation, which had only feeders from the left middle meningeal and occipital artery.
These findings were confirmed surgically. This case is not only rare, but also interesting in terms of the pathogenesis of the arteriovenous malformation.
