Congenital Hypoplasia of Bilateral Internal Carotid Artery with Migraine-Like Headache with Aura

Abstract

To the Editor: A 36-year-old man with intermittent migraine-like headache with aura for 20 years underwent cerebrovascular computed tomography angiography (CTA) revealing very small calibers of bilateral internal carotid arteries (ICAs) in other hospital. Transcranial doppler examination showed increased mean flow velocities (MFVs) in the bilateral posterior cerebral arteries (right, 75.5 +- 1.3 cm/s; left, 73.5 +- 1.3 cm/s) compared with the bilateral middle cerebral arteries in the headache-free period (right, 54.5 +- 2.4 cm/s;...
