[Wyburn-Mason syndrome].
BACKGROUND
The Wyburn-Mason or Bonnet, Dechaume, and Blanc syndrome is a rare congenital anomaly formed of malformations of the retinal vessels, orbito-cerebral vessels, and, rarely, facial vessels.


METHODS
Male patient, 19 years old, examined because of a severe visual loss and exophthalmos at the left eye. The ophthalmoscopic examination reveals extensive retinal arterio-venous malformations, also confirmed at orbito-cerebral level by ultrasound and MRI DISCUSSION: The Wyburn-Mason syndrome is due to arterio-venous anastomosis, being included in the phakomatosis group. Clinically we describe 3 groups of severity. Aspects of differential diagnosis, pathogeny, and treatment are discussed.


CONCLUSIONS
The Wyburn-Mason syndrome can be suspected in cases of facial angioma, exophthalmos, or decreased visual acuity. The diagnosis imposes additional examinations with orbito-cerebral imagery.
