We report the case of a 47-year-old woman with a sudden, spontaneous exsang
uinating haemorrhage from an arteriovenous malformation of the mandible. Th
e diagnosis was obtained with a contrast enhanced CT-scan and a digital sub
traction angiography. As arterial embolisation was not available the lesion
was treated surgically. (C) 1999 Elsevier, Paris.
