( A ) Clinical photograph of a 48-year-old man with arteriovenous malformation (AVM) of the left orbit, involving medial preseptal soft tissues. ( B ) T1-weighted magnetic resonance imaging (MRI) with fat saturation illustrates flow voids. ( C ) T1-weighted MRI with contrast demonstrates diffuse contrast enhancement. ( D ) In the cranial projection of the left external carotid artery angiogram, the AVM's primary supply arises from the ophthalmic artery, superficial temporal artery and facial artery (angular branch).
