Dacryocystocele or lacrimal duct cyst is a benign mass resulting from a congenital obstruction of the lacrimal system. These cystic masses can be detected sonographically after 30 weeks menstrual age. This case study presents ultrasound diagnosis of the dacryocystocele at 33.5 weeks menstrual age after multiple previous sonograms, demonstrating normal fetal facial anatomy.
