[Diagnosis of an aneurysm of the great cerebral vein of Galen using duplex sonography].

The combination of two-dimensional sonography of the skull and pulsed Doppler measurements (= Duplex-scan-technique) was used to detect an aneurysm of the vein of Galen in a three months old infant, who presented with clinical signs of congestive heart failure. Excellent correlation of sonography with computed tomography and intravenous digital subtraction angiography could be demonstrated. A short review of the pathological and clinical findings of this lesion is given. The value of Duplex-scanning in the diagnostic approach of arterio-venous malformations of the brain in comparison with other radiological methods is discussed.
