[Dacryocystocele. Prenatal ultrasonic diagnosis]

The authors report a case of bilateral dacryrocystocele (lacrimal duct obstruction) in a fetus of 32 weeks amenorrhoea, diagnosed by ultrasound. This pathology has been rarely described in a fetus although it is relatively frequent in the new born. This case has made it possible for the authors to define the ultrasound appearances and the prognosis.
