The presence of cystic dilation of the lacrimal drainage system (dacryocystocele) in the fetus must be differentiated from less benign paraocular masses.

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.
