Abstract
Using combined echoencephalography and Doppler flow determination the diagnosis Arteriovenous aneurysm of the great cerebral vein of Galen could be made in two infants. Without vascular surgery one patient died, the other recovered completely. CT scanning confirmed the diagnosis. Invasive methods such as cerebral angiography were avoided. Case histories, neuropathological findings, ultrasound method and results are presented. Pathogenesis, clinical signs, treatment and prognosis are discussed. With the ultrasound method presented, the nature and location of the vascular anomaly were demonstrable, thus additional higher risk diagnostic methods could be avoided or planned more purposefully.
