Bilateral congenital absence of the internal carotid artery

Abstract. Bilateral congenital absence of the internal carotid artery was incidentally found in an 11-year-old boy. Magnetic resonance imaging showed a normal-appearing brain that was entirely supplied by the vertebrobasilar system, and CT confirmed the absence of the bony carotid canals. Although most reported patients with agenesis of both internal carotid arteries presented with cerebrovascular lesions, this case demonstrates that this rare malformation may be asymptomatic.

Triple blowout fracture of the orbit

Abstract We describe a case of traumatic orbital fracture involving the superior, medial, and inferior walls with preserved orbital rim. This “triple blowout” fracture has not been previously reported. There was no damage to the globe or the optic nerve and the patient had an excellent recovery with minimal residual diplopia.
