| Abstract: | A rare case of an arteriovenous malformation involving the optic chiasm associated with vascular anomaly in the left maxillary region is presented. The angiogram demonstrated an arteriovenous malformation arising from the anterior circle of Willis (internal carotid, posterior communicating, and proximal anterior cerebral arteries), and located in the region of the optic chiasm and hypothalamus. The case was diagnosed as the Bonnet-Dechaume-Blanc syndrome without intraorbital and retinal arteriovenous malformations. The suprasellar arteriovenous malformation was removed, except for a small portion in the hypothalamus, with satisfactory results. |
