The "seagull cry" in a patient with a cerebral arteriovenous malformation.

ABSTRACT:

Introduction

The "seagull cry" is an acoustic phenomenon heard during duplex ultrasound. It is caused by harmonic covibrations of a vessel wall in the presence of high-velocity blood flow. It has been reported in a few cases of cerebrovascular disease, such as severe intracranial stenosis, vasospasm or carotid-cavernous fistula.

Material and methods

A 35-year-old man underwent transcranial color-coded sonography (TCCS) for work-up of a severe new-onset headache.

Results

Doppler spectral analysis of the right intracranial carotid bifurcation revealed multiple pairs of mirror-image parallel strings, and a high-frequency seagull cry was heard. Computed tomography-angiography and magnetic resonance imaging of the brain showed an arteriovenous malformation in the right tem
