Congenital dilatation of the nasolacrimal sac (Dacryocystocele): Case report.

Congenital dacryocystoceles are usually diagnosed in the third trimester by parental ultrasound as a cystic lesion adjacent to the medial and inferior aspects of the fetal orbit. A considerable number of dacryocystocele are bilateral and resolve spontaneously in utero and/or immediately after delivery. Persistent dacryocystoceles need ophthalmological consultation to avoid the possible potential complications. This case report represents a case of congenital dacryocystocele diagnosed by antenatal 2D and 3D ultrasounds, which disappeared spontaneously 2 days after birth. To highlight that, the diagnosis of congenital dacryocystoceles is important to avoid additional postnatal diagnostic techniques and to manage the potential postnatal complications.
