title: Magnetic resonance imaging in prenatal diagnosis of dacryocystocele: report of 3 cases.
abstract: The presence of cystic dilation of the lacrimal drainage system (dacryocystocele) in the fetus must be differentiated from less benign paraocular masses. Three cases of dacryocystocele studied during fetal life by ultrasound and magnetic resonance (MR) imaging are reported. The accuracy of prenatal MR imaging facilitated a definite diagnosis depicting the characteristic triad of dacryocystocele: paraocular cystic mass in the medial canthus region, nasolacrimal duct enlargement, and intranasal cyst.
