title: Prenatal diagnosis of bilateral dacryocystocele using 3-D/4-D ultrasound technology: a case report.
abstract: BACKGROUND
  Bilateral dacryocystoceles develop as a result of obstruction of the nasolacrimal canal. The advances in obstetric sonography have led to increased diagnosis of this structural defect in the antenatal period as early as 24 weeks' gestation.
  
  
  METHODS
  We describe a case of bilateral dacryocystocele with clear visualization of this defect using 3-D/4-D sonography.
  
  
  CONCLUSIONS
  Optimal visualization of this lesion using 3-D/4-D sonogram is helpful in providing better distinction of this lesion from other fetal facial lesions and can provide reassurance to anxious parents.
