Antenatal sonographic diagnosis of dacryocystocele.
Dacryocystocele is an uncommon condition presenting at birth as a bluish swelling approximately 1 cm in diameter located below and nasal to the medial canthus. It represents a cystic swelling of the lacrimal sac due to obstruction of the lacrimal drainage system both above and below the sac. The average age when the lacrimal duct becomes patent is the eighth intrauterine month. If this does not occur, a dacryocystocele can result. Dacryocystocele is also referred to in the literature as mucocele, dacryocele, and amniocele of the lacrimal sac. We report a case of a dacryocystocele detected sonographically during pregnancy.
