Color and pulsed Doppler echography was used in patients with an arteriovenous malformations (AVM) of the tongue, floor of the mouth and mandible and with a hemangioma of the tongue, respectively. Color Doppler echographs of the AVM displayed a mosaic pattern with color flow signals in the nidus, whereas those of the hemangioma showed a monotonous pattern with color flow signals in the lesion. Pulsed Doppler echographs of the AVM delineated pulsatile waves of feeding arteries and drainage veins, while those of the hemangioma did not show evidence of drainage veins. Waves of feeding arteries were similar to those of drainage veins in the pulsed Doppler echographs for the AVM, which suggested the presence of an arteriovenous shunt.<BR>The results of this investigation indicated that color and pulsed Doppler echography is useful for the differential diagnosis of vasculr disease in the oral and maxillofacial region.
